   Today is the sacred महा अवतार जयन्ति (mahā avatāra jayanti - sacred incarnation anniversary) of His Holiness जगत् गुरु श्री आदि शंकराचार्य भगवर्पाद (jagat guru śrī ādi śaṁkarācārya bhagavarpāda). He is one of the noblest of saintly gurus who walked on earth. He is aptly respected as the जगत् गुरु (jagat guru - universal preceptor) because of his unparalleled contribution to universal religio-spiritual heritage. To quote Swami Vivekananda : 

“India has to live, and the spirit of the Lords descended again. He who declared, "I will come whenever virtue subsides", came again, and this time the manifestation was in the South, and up rose that young brahmin of whom it has been declared that at the age of sixteen he had completed all his writings; the marvelous boy Shankaracharya arose. The writings of this boy of sixteen are the wonders of the modern world, and so was the boy. He wanted to bring back the Indian world to its pristine purity, but think of the amount of the task before him…. The greatest teacher of the Vedanta philosophy was Shankaracharya. By solid reasoning he extracted from the Vedas the truths of Vedanta, and on them built up the wonderful system of Jnana that is taught in his commentaries. He unified all the conflicting descriptions of Brahman and showed that there is only one Infinite Reality. He showed too that as man can only travel slowly on the upward road, all the varied presentations are needed to suit his varying capacity."

    On this sacred day, I am reminded of the following verses often quoted by the Holy Sage of Kanchi, His Holiness ஸ்ரீ மஹா பெரியவா (srī mahā periyavā) and recorded in his தெய்வத்தின் குறள் (deivattiṉ kuṟaḷ - voice of god)

Original	Transliteration	Translation
शास्त्रं शरीरमीमांसा देवस्तु परमेश्वरः। आचार्यः शंकराचार्यः सन्तु जन्मनि जन्मनि॥	śāstraṃ śarīramīmāṃsā devastu parameśvaraḥ। ācāryaḥ śaṃkarācāryaḥ santu janmani janmani॥	If. in every future birth, the sheet-anchor of my faith and understanding is the religion of the Upanishads, If the God I worship is Parameshvara Himself, if the Guru who will be my refuge is Sri Shankaracharya, it does not matter how many births I am to take. May these three be granted to me life after life.

    Yes, श्री आदि शङ्कराचार्य भगवत्पाद (śrī ādi śaṅkarācārya bhagavatpāda) was one of the earliest pioneers in उत्तरमीमांसावेदान्तदर्शन (uttaramīmāṃsāvedāntadarśana– posterior inquiry final-gnosis philosophy), who gifted us with the philosophical treasure-house viz. केवलाद्वैतवेदान्तदर्शन (kevalādtvaitavedāntadarśana – absolute non-dualistic final-wisdom philosophy) very emphatically establishing that the सच्चिदानन्द परब्रह्मन् (satcitānanda parabrahman – omnicient omnipotent omnibliss absolute divinity) is the one and only नित्य कैवल्य सत्य (nitya kaivalya satya - eternal absolute reality) To borrow Swami Vivekananda's famous verses - 

"Each soul is potentially divine" and "Religion is the manifestation of (this potential) divinity already in man." 

Birth details

According to the traditional वाक्यपञ्चाङ्ग (vākyapañcāṅga – revealed almanac), the sacred annual event of श्री आदि शंकराचार्य महाजयन्ति (śrī ādi śaṃkarācārya mahājayanti) which commemorates the महावतारदिन (mahāvatāradina – supreme incarnation day) of His Holiness जगत् गुरु श्री आदि शंकराचार्य भगवर्पाद (jagat guru śrī ādi śaṁkarācārya bhagavarpāda) is observed on the शुक्लपक्ष पञ्चमीतिथि वैशक मासस्य (śuklapakṣa pañcamītithi vaiśaka māsasya – fifth lunar day of waxing fortnight) occurring in the month of वैशाखमास (vaiśākhamāsa – mid April-mid May month). 

    परमाचार्य श्री माधवविद्यारण्य स्वामिन् (paramācārya śrī mādhavavidyāraṇya svāmin) in his famous hagiographical treatise called संक्षेपशंकरविजय (saṃkṣepaśaṃkaravijaya) more popularly known by the name शंकरदिग्वैजय (śaṃkaradigvaijaya) records thus:

Original	Transliteration	Translation
लग्नेशुभे शुभयुते सुषुवे कुमारं श्री पार्वतीव सुखिनी शुभवीक्षिते च । जाया सती शिवगुरोः निजतुङ्ग संस्ते सूर्येकुजे रविसुते च गुरौचकेन्द्रे ॥	lagneśubhe śubhyute suṣuve kumāraṃ śrī pārvatīva sukhinī śubhavīkṣite ca। jāyā satī śivaguroḥ nijatuṅga saṃste sūryekuje ravisute ca guraucakendre॥	The Lagna was fully aspected by the benign planets like Guru Mars, Sun and Saturn were exalted and Guru was at the zenith. It was an easy delivery, as if Parvathi were giving birth to Skanda. At the sight of his son's face, Sivaguru was drowned in a sea of joy. -translation by Swami Tapasyananda (RKM Order)
Sanskrit Reference: संक्षेपशंकरविजय / शंकरदिग्वैजय (saṃkṣepaśaṃkaravijaya / śaṃkaradigvaijaya) (2.71)

            According to traditional account as provided in scriptures like the शिवरहस्य (śivarahasya), शशलग्राम (śaśalagrāma) which now forms part Cochin/Ernakulam district in the state of Kerala. In the शंकरदिग्वैजय (śaṃkaradigvaijaya) refers to the name of this village as कालडि/कालटि (kālaḍi/kālaṭi).

While there are not much disputes regarding the जन्म/अवतारस्थल (janma/avatārasthala – place of birth / incarnation) amongst traditionalists and historians, there are major disagreements when it comes to His वर्ष जन्मस्य (varṣa janmasya – year of birth) as well as the place of his समाधिस्थल (samādhisthala – atonement place). While the orthodox accounts trace his birth to the year 509 BC / BCE, the more conservative versions of modern historians trace his year of birth to around 648 AD/CE

For example, आचार्य श्री आत्मबोध (ācārya śrī ātmabodha) in his famous hagiographical treatise by name प्राचीनशंकरविजय (prācīnaśaṃkaravijaya) traces the वर्ष जन्मस्य (varṣa janmasya – year of birth) as follows 

Original	Transliteration	Translation
तिष्ये प्रयात्यनलशेवधिबाणनेत्रे यो नन्दने दिनमणावुदगध्भाजि। राधेऽअदितेरुडुनि निर्गतमस्तलग्ने प्याहूत्वान्शिवगुरुः स च शङ्करेति॥	tiṣye prayātyanalaśevadhibāṇanetre yo nandane dinamaṇāvudagadhbhāji। rādhe'aditeruḍuni nirgatamastalagne pyāhūtvānśivaguruḥ sa ca śaṅkareti॥	After the onset of kaliyuga, in the 2593rd year called Nandana Samvatsara, on the fifth-lunar day in mid April during the summer solstice (uttarayaṇa vaiśāka śuddha pañcamīthithi) in the Caste/Pollux asterism (punarvasu nakṣatra) and karkaṭakalagna (kataka ascendent), he was born of Śivaguru, who named him Śankara. -based on translation of Dr. H. Ramachandra Swami

The following is the sacred जनंकुण्डली आदिशंकराचार्यस्य (janaṃkuṇḍalī ādiśaṃkarācāryasya – natal chart of Adi Shankaracharya) according to B.V. Raman, the eminent astrologer

अवतार ईश्वरस्य (avatāra īśvarasya – incarnation of god)

श्री आदिशंकराचार्यभगवत्पाद (śrī ādiśaṃkarācāryabhagavatpāda), according to the orthodox वैदिकसंप्रदाय (vaidikasaṃpradāya – vedic tradition), is not considered as a mere माणुष्यगुरु (māṇuṣyaguru – human  preceptor) but rather, as the साक्षात् अवतार ईश्वरस्य (sākṣāt avatāra īśvarasya – direct incarnation of god).

श्री आदिशंकराचार्यभगवत्पाद (śrī ādiśaṃkarācāryabhagavatpāda), according to the orthodox वैदिकसंप्रदाय (vaidikasaṃpradāya – vedic tradition), is not considered as a mere माणुष्यगुरु (māṇuṣyaguru – human  preceptor) but rather, as the साक्षात् अवतार ईश्वरस्य (sākṣāt avatāra īśvarasya – direct incarnation of god).

For instance, it is a widely accepted belief that the जगद्गुरु (jagadguru – universal preceptor) is none other than the देवमीढांश श्री परमशिवस्य (devamīḍhāṃśa śrī paramaśivasya –god-begotten fractal of Lord Parama-Shiva).This fact is testified by various scriptures including the traditional hagiographical treatises on the saint. For example, the following verses from the sacred शिवरहस्य (śivarahasya) categorically testifies thus: 

Original	Transliteration	Translation
पापकर्मैकनिरतां विरतान् सर्वकर्मसु॥ वर्णाश्रमपरिभ्रष्टान् धर्मप्रस्रवान् जनान्। कल्यब्धौ मज्जमानांस्तान् दृष्टवानुक्रोशतोम्बिके॥ मदंशजातं देवेशि कलावपि तपोदनम्। केरलेषु तदा विप्रं जनयामि महेश्वरि॥ …. तेषामुत्पाटनार्थाय सृजामीशे मदम्शतः॥ केरले शशलग्रामे विप्रपतन्यां मदंशतः। भविष्यति महदेवि शङ्कराख्यो द्विजोत्तमः॥ उपनीतस्तदा मात्रा वेदान् साङ्गान् ग्रहिष्यति।	pāpakarmaikaniratāṃ viratān sarvakarmasu॥ varṇāśramaparibhraṣṭān dharmaprasravān janān। kalyabdhau majjamānāṃstān dṛṣṭavānukrośatombike॥ madaṃśajātaṃ deveśi kalāvapi tapodanam। keraleṣu tadā vipraṃ janayāmi maheśvari॥ teṣāmutpāṭanārthāya sṛjāmīśe madamśataḥ॥ kerale śaśalagrāme viprapatanyāṃ madaṃśataḥ। bhaviṣyati mahadevi śaṅkarākhyo dvijottamaḥ॥ upanītastadā mātrā vedān sāṅgān grahiṣyati।	Observing the people bent upon committing sins, disinterested in all the rites, having fallen of from the regulations of class and stages of life, sliding down from righteousness, with compassion on them , O Ambika, Deviśi, Maheśvari, I shall from my own part, cause the birth of a pious brahmin in Kerala. …. In order to destroy them O Ishvari, I shall part from my own and create: a pious brahmin by name Śankara shall be born in Kerala in Śaśalagrāma, from (the womb of) a brahmin’s wife. Getting the sacred thread from his mother, he will grasp the Vedas and Vedaṅgas. -translation by Dr. H. Ramachandra Swami (Adyatma Prakasha Karyalaya)
Sanskrit Reference: शिवरहस्य (śivarahasya)

Again, श्री अनन्तानन्दगिरि (śrī anantānandagiri) in his famous अनन्तानन्दगिरीयशंकरविजय (anantānandagirīyaśaṃkaravijaya) also clearly establishes this fact that श्री आदिशंकराचार्यभगवत्पाद (śrī ādiśaṃkarācāryabhagavatpāda) was non other than the अंशावतारपरमशिवस्य (aṃśāvatāraparamaśivasya – partial incarnation of Lord Parama Shiva). 

गुरुपरंपरा (guruparaṃparā -preceptor-lineage)

    In fact, not only the श्री आदिशंकराचार्यभगवत्पाद (śrī ādiśaṃkarācāryabhagavatpāda), but the entire गुरुपरंपरा स्मार्तमतसंप्रदायस्य (guruparaṃparā smārtamatasaṃpradāyasya – preceptor-lineage of Smarta theological tradition)  has direct divine association as depicted in the below chart:  

 Traditionally, श्री आदि शङ्कराचार्य भगवत्पाद (śrī ādi śaṅkarācārya bhagavatpāda) belongs to the स्मार्तमतसंप्रदाय (smārtamatasaṃpradāya - smartha theological tradition). Hence , we shall first look at the गुरुपरंपरा स्मार्तमतसंप्रदायस्य (guruparaṃparā smārtamatasaṃpradāyasya – preceptor-lineage of Smarta theological tradition).  For example, 

   For example, the गुरुपरंपरा (guruparaṃparā – preceptor-lineage) depicted in the above chart is endorsed in the गुरुवंशकाव्य (guruvaṃśakāvya) which is a famous treatise written by श्री काशी लक्ष्मणशास्त्री (śrī kāśī lakṣmaṇaśāstrī) traces the following गुरुपरंपरा (guruparaṃparā – preceptor-lineage) with respect to the श्री शृङ्गेरी शारदा पीठं (śrī śṛṅgerī śāradā pīṭhaṁ- shri shringeri sharada pitham).

    A similar lineage is also mentioned in the गुरुरत्नमाल (gururatnamāla) - a famous treatise composed by His Holiness श्री सदाशिव ब्रह्मेन्द्र सरस्वती (śrī sadāśiva brahmendra sarasvatī) who was the षट्पञ्चाश पीठाधिपति श्रीकाञ्चिकामकोटि पीठस्य (ṣaṭpañcāśa pīṭhādhipati śrīkāñcikāmakoṭi pīṭhasya – fifthy-sixth pontiff ofSri Kanchi Kamakoti Pitham)

    While the above chart depicts the overall गुरुपरंपरा स्मार्तमतसंप्रदायस्य (guruparaṃparā smārtamatasaṃpradāyasya – preceptor-lineage of Smarta theological tradition), from a philosophical standpoint of advocators of the केवलाद्वैतवेदान्तदर्शन , the गुरुपरंपरा (guruparaṃparā – preceptor lineage) can be classified as follows:

: 

 दिग्विजययात्र (digvijayayātra – global conquest pilgrimage) 

    Again, through his दिग्विजययात्र (digvijayayātra – global conquest pilgrimage) by travelling the four across cardinal directions including the चार्धम् (caturdham – four abodes) and thereby covering the length and breadth of भारतव्रश (bhāratavraśa – Indian sub-continent)   

        According to the traditional account of  श्री काञ्ची कामकोटि पीठं (śrī kāñcī kāmakoṭi pīṭhaṁ), the following are the places visited by  श्री आदिशंकराचार्यभगवत्पाद (śrī ādiśaṃkarācāryabhagavatpāda) as part of his दिग्विजययात्र (digvijayayātra – global conquest pilgrimage)

The noble saint and Sage of Kanchi, परमाचार्य श्री चन्द्रशेकरेन्द्र सरस्वती (paramācārya śrī candraśekarendra sarasvatī) summarizes thus about the दिग्विजययात्र  श्री आदिशंकराचार्यस्य (digvijayayātra śrī ādiśaṃkarācāryasya – global conquest pilgrimage):

 Thus the Parivrat (wandering monk), who expounds the hidden meaning of the Upanishads in the words of his commentaries which are clear and deep, wanders about.  He wanders everywhere from the Setu to the Himalayas.  He visits the holy rivers.  He goes to the pilgrim-places.  He tours the villages.  He goes to the towns.  He visits the temples.  In those places, he augments the Presence Divine through such means as mantras and yantras.  There is almost no holy place in India whose greatness has not been strengthened by Sankara’s visit.  Even to this day people in the different parts of the country say:  “This temple in our territory has been purified by the splendor of the mantra uttered by Sri Sankaracharya; and has been rendered great by the installation of yantras.”  In the entire area where the Veda has spread –– Anga, Vanga, Kalinga, Andhra, Dravida, Kerala, Karnataka, Maharashtra, Saurashtra, Malava, Gurjara, Sindhu, Gandhara, Kuru, Panchala, Kasmira, Nepala, Maithila, Kanyakubja, Magadha, Kamarupa, Kamboja, etc. –– there is no place where the Bhashya of Sri Sankaracharya was not known to the seekers of release.  Even now it is so in every place where the Veda is in vogue.

 

अमानया विद्यामठ (amānāya vidyāmaṭha – traditional / orthodox monastic schools) 

Eventually, he is known to have established अमानया विद्यामठ (amānāya vidyāmaṭha – traditional / orthodox monastic schools) across India. He then formally designated chosen four of his principle disciples, entrusting them the responsibility of heading and manage these establishments. मठांनायसेतु महाणुशासनं (maṭhāṃnāyasetu mahāṇuśāsanaṃ - monastic order league commandment) is traditionally important treatise governing the by-laws of the आम्नायविद्यामठाः (āmnāyavidyāmaṭhāḥ – traditional monastraries).

The contribution of श्री आदिशंकराचार्यभगवत्पाद (śrī ādiśaṃkarācāryabhagavatpāda) does not stop with fomally  establishing the आम्नायविद्यामठाः (āmnāyavidyāmaṭhāḥ – traditional monastraries) or even दशनामी सम्प्रदाय (daśanāmī sampradāya – ten names tradition). He also played a pivotal role in creating a formal defence system against the breaking forces of सनातनधर्म हिन्दुसमयस्य (sanātanadharma hindusamayasya – eternal soirituality of hindu religion).

For example, he was one of the pioneers in establishing what is called as the नागसंन्याससंप्रदाय (nāgasaṃnyāsasaṃpradāya – snake ascetic tradition) who are technically अस्त्रधारिणः (astradhāriṇaḥ - weapon holders).  In other words, the दशनामी सम्प्रदाय (daśanāmī sampradāya – ten names tradition) was further categorized into two groups viz. the traditional शास्त्रधारिणः (śāstradhāriṇaḥ- scripture holders) on the one hand who ensure in intelectual protection of  सनातनधर्म हिन्दुसमयस्य (sanātanadharma hindusamayasya – eternal soirituality of hindu religion)  while there were the नागसाध्वः (nāgasādhvaḥ - snake saints) who provided the physical defence to the same.

Historically speaking, each of the above आम्नायविद्यामठाः (āmnāyavidyāmaṭhāḥ – traditional monastraries) provided formal military (self-defence training) to the नागसाध्वः (nāgasādhvaḥ - snake saints) at the रक्षा अखाडा (rakṣā akhāḍā – defence academy). For example,  अवाहन् अखाडा (avāhan akhāḍā), अटल अखाडा (aṭala akhāḍā), निर्वाणि अखाडा (nirvāṇi akhāḍā), भैरवी अखाडा (bhairavī akhāḍā), आनन्द अखाडा (ānanda akhāḍā) & निरञ्जनी अखाडा (nirañjanī akhāḍā) are some famous ancient examples. 

 Having established the four monasteries, श्री आदि शङ्कराचार्य भगवत्पाद (śrī ādi śaṅkarācārya bhagavatpāda) himself became the प्रथम पीठाधिपति (prathama pīṭhādhipati – first chairperson) of the श्री काञ्ची कामकोटि पीठं (śrī kāñcī kāmakoṭi pīṭhaṁ) which is considered as the सर्व ज्ञान पिठ (sarva jñāna piṭha – throne of omniscience).

    It is also widely believed that श्री आदि शङ्कराचार्य भगवत्पाद (śrī ādi śaṅkarācārya bhagavatpāda)  was instrumental in constructing the sacred श्री काञ्चीकामाक्षी दिव्यक्षेत्र (śrī kāñcīkāmākṣī divyakṣetra – sacred Kanchi Kamakashi temple)  and formally consecrating the श्रीचक्रयन्त्रमण्डल (śrīcakrayantramaṇḍala) before ascending the सर्व ज्ञान पिठ (sarva jñāna piṭha – throne of omniscience). This fact is testified through various authentic orthodox sources. For example, श्री मार्कण्डेयमहापुराण संहिता (śrī mārkaṇḍeyamahāpurāṇa saṃhitā) very categorically eshtablishes this fact. Again, परमाचार्य श्री माधवविद्यारण्य स्वामिन् (paramācārya śrī mādhavavidyāraṇya svāmin) in his famous hagiographical treatise called संक्षेपशंकरविजय (saṃkṣepaśaṃkaravijaya), more popularly known by the name शंकरदिग्वैजय (śaṃkaradigvaijaya) records thus:

There he built a temple, instituted the worship of Devi, with rituals that are in accordance with the Vedic traditions and suited to the attainment of supreme knowledge. He eschewed, in those rituals, every trace of the Tāntrika modes of worship... -translation by Swami Tapasyananad (RKM Order)
Sanskrit Reference: संक्षेपशंकरविजय (saṃkṣepaśaṃkaravijaya) (15.4,5)

The formal consecration of श्रीचक्रयन्त्रमण्डल (śrīcakrayantramaṇḍala) is also testified by both श्री चिद्विलासाचार्य (śrī cidvilāsācārya) and श्री आनन्दगिरियाचार्य (śrī ānandagiriyācārya) in their famous hagiographical treatises called चिद्विलासियशंकरविजय (cidvilāsiyaśaṃkaravijaya) &  श्री आनन्दगिर्यशंकरविजय  (śrī ānandagiryaśaṃkaravijaya) respectively. 

        By establishing these monastic orders  श्री आदि शङ्कराचार्य भगवत्पाद (śrī ādi śaṅkarācārya bhagavatpāda) also played a pivotal role in integrating the pan Indian cultural belief systems across Hindus into common identity as one religion - हिन्दुधर्म (hindudharma - Hinduism). 

        Again, श्री आदि शङ्कराचार्य भगवत्पाद (śrī ādi śaṅkarācārya bhagavatpāda) following the foot steps of श्री व्यास महऋषि (śrī  vyāsa mahaṛṣi) established the inherent divinity in all phenomenal manifestation reflecting the wisdom of the महावाक्यानि (mahāvākyāni - supreme declarations), as revealed in the चतुर्वेदसंहिताः (caturvedasaṃhitāḥ - four vedic corpuses)

#	वेदसंहिता (vedasaṃhitā – vedic corpus)	मुख्योपनिषद् (mukhyopaniṣad – principal upanishad)	महावाक्य (mahāvākya – supreme vedict)
1	ऋग्वेदसंहिता (ṛgvedasaṃhitā)	ऐतरेयोपनिषद् (aitareyopaniṣad)	प्रज्ञानम् ब्रह्म (prajñānam brahma – God is absolute wisdom)

4	अथर्वणवेदसंहिता (atharvaṇavedasaṁhitā)	माण्डुक्योपनिषद् (māṇḍukyopaniṣad)	अयम् आत्मा ब्रह्म (ayam ātmā brahma - this self is God)

    In fact, in the small treatise वाक्य वृत्तिः (vākya vṛttiḥ), the आचार्य (ācārya - preceptor) preaches the spiritual significance of महा वाक्य (mahā vākya - supreme declarations) especially on तत् त्वम् असि (tat tvam asi - thou art that) & अहं ब्रह्मास्मि (ahaṁ brahmāsmi - I am Divine)
In a nutshell, श्री आदि शंक्राचार्य (śrī ādi śaṁkrācārya) helped drive home the spiritual message of Universal Divinity irrespective one’s caste, creed, religion, nationality etc. The following verses from his मनिषा पञ्चकम् (maniṣā pañcakam – five fold considerations) very clearly highlights his universal non-dualistic outlook.

Original	Transliteration	Translation

This is my firm conviction I am pure Consciousness, and this entire universe, is only an expansion of pure Consciousness Out of this Maya all this that we see, made of the three gunas, has been conjured by imagination, He whose intellect is firmly established in the all blissful, eternal, Supreme Reality, be he a Chandala or be he a Brahmana, such a one is indeed worthy of being a Guru. This is my firm conviction

Moreover, according to श्री आदि शङ्कराचार्य भगवत्पाद (śrī ādi śaṅkarācārya bhagavatpāda), it is our अविद्यामाया  (avidyāmāyā- nescient mystery) that hides our divine potential and limits us to the confines of अहंकार (ahaṁkāra - self arrogation) leading to अहमिदम्भेद (ahamidambheda – I–this difference).
    In my humble opinion, श्री आदि शङ्कराचार्य भगवत्पाद (śrī ādi śaṅkarācārya bhagavatpāda) is truly a जगत्गुरु (jagat guru - universal preceptor) in this sense as well. He helped us realize that all kinds of disparities are temporary and unity is the permanent reality. With the dawn of spiritual enlightenment (wisdom), differences across all phenomenal manifestations across the world can potentially be integrated into the कैवल्य अद्वैत एकत्वम् (kaivalya advaita ekatvam - absolute non dual singularity). Interestingly, recent discoveries in modern physics also echoes a similar concept of absolute cosmic singularity.
    Of course his contribution to spirituality does not end here. He is also one of the greatest pan-Indian holistic synthesizers of heterogeneous theological / philosophical schools viz. वैदीक (vaidīka - vedic), तान्त्रिक (tāntrika - tantrik), आगम (āgama - agamic),पुराण (purāṇa - mythological) etc. into a homogeneous system of Hindu philosophy. He also wisely incorporated the learning and best practices from योगदर्शन (yogadarśana), सांख्यदर्शन (sāṃkhyadarśana), वैशेषिकदर्शन (vaiśeṣikadarśana), न्यायदर्शन (nyāyadarśana), पूर्वमीमांसदर्शन (pūrvamīmāṃsadarśana), उत्तरमीमांसदर्शन (uttaramīmāṃsadarśana). 

He also helped in a two way (both from & to) wisdom adoption with other popular heterodox religions of his times - बौद्धधर्म (bauddhadharma - Buddhism) and जैनधरम (jainadharama - Jainism) etc., into mainstream हिन्दुधर्म (hindudharma - Hinduism). To quote Dr. Sarvepalli S Radhakrishnan: 

 "Sankara present to us the true ideal of philosophy, which is not so much knowledge as wisdom, not so much logical learning as spiritual freedom. For Sankara, as for some of the greatest thinkers of the world like Plato and Plotinus, Spinoza and Hegel, Philosophy is the austere vision of eternal truth, majestic in its freedom from the petty cares of man's paltry life. Through the massive and at the same time subtle dialectic of Sankara there shows forth a vivid, emotional temperament, without which philosophy tends to become a mere game of logic. A master of the strictest logic, he is also master of a noble and animated poetry which belongs to another order. The rays of his genius have illumined the dark places of thought and soothed the sorrows of the most forlorn heart. While his philosophy fortifies and consoles many, there are, of course, those to whom it seems to be an abyss of contradiction and darkness. But whether we agree or differ, the penetrating light of his mind never leaves us where we were....Sankara appeared, at one and the same time, as an eager champion of the orthodox faith and a spiritual reformer. He tried to bring back the age from the brilliant luxury of the Puranas to the mystic truth of the Upanishads. The power of the faith to lead the soul to the higher life became for him the test of its strength. He felt impelled to attempt the spiritual direction of his age by formulating a philosophy and religion which could satisfy the ethical and spiritual needs of the people".

शास्त्रीय योगदान (śāstrīya yogadāna – scriptural contribution)

श्री आदिशंकराचार्य भगवद्पाद (śrī ādiśaṁkarācārya bhagavadpāda) has made unparalleled contribution to the भारतीयसनातनधर्म (bhāratīyasanātanadharma – Indian eternal spirituality) by creating a huge corpus of scriptural treatises, which is estimated to be around 153 in number  including 

#	Category	Count
1	भाष्य ग्रन्थाः (bhāṣya granthāḥ - commentary treatises)	23
2	प्रकरण ग्रन्थाः (prakaraṇa granthāḥ - explanatory treatises)	54
3	स्तोत्र स्तुति ग्रन्थाः (stotra stuti granthāḥ - eulogical treatizes)	76
Total		153

    Some of the important शास्त्रीय ग्रन्थाः (śāstrīya granthāḥ - scriptural treatises)  that are attributed to श्री आदिशंकराचार्य भगवद्पाद (śrī ādiśaṁkarācārya bhagavadpāda) can further be classified  as follows 

 He also helped in consolidating the huge corpus of Vedic scriptures and streamlining their underlying philosophic essence by writing भाष्याणि (bhāṣyāṇi - commentaries) on the प्रस्थानत्रयी (prasthāna trayī – triple sources) of orthodox Hindu scriptures viz.   

#	प्रस्थान शास्त्र (prasthāna śāstra- source scripture)	Focus
1	मुख्योपनिषदः (mukhyopaniṣadaḥ)	श्रुति प्रस्थान (śruti prasthāna – scriptural source)
2	ब्रह्म सूत्र / शारीरक सूत्र (brahma sūtra / śārīraka sūtra)	युक्ति प्रस्थान (yukti prasthāna – logical source)
3	श्रीमद् भगवद्गीता (śrīmad bhagavadgītā)	साधन प्रस्थान (sādhana prasthāna – instrumental source)

     Let's take the मुख्योपनिषदः (mukhyopaniṣadaḥ - principal upanishads) which are technically categorized as श्रुति प्रस्थान (śruti prasthāna – scriptural source). It is widely believed that श्री आदि शङ्कराचार्य भगवत्पाद (śrī ādi śaṅkarācārya bhagavatpāda) has written these detailed commentaries 

#	भाष्य (bhāṣya - commentary)
1	ऐत्रेय उपनिषद् भाष्य (aitreya upaniṣad bhāṣya)
2	बृहदारण्यक उपनिषद् भाष्य  (bṛhadāraṇyaka upaniṣad bhāṣya)
4	छाण्दोग्य उपनिषद् भाष्य  (chāṇdogya upaniṣad bhāṣya)
5	ईश उपनिषद् भाष्य  (īśa upaniṣad bhāṣya)
6	कथोपनिषद् भाष्य (kaṭhopaniṣad bhāṣya)
7	केन उपनिषद् भाष्य (kena upaniṣad bhāṣya)
9	माण्डूक्य उपनिषद् भाष्य (māṇḍūkya upaniṣad bhāṣya)
10	मुण्डक उपनिषद् भाष्य (muṇḍaka upaniṣad bhāṣya)
11	प्रश्न उपनिषद् भाष्य (praśna upaniṣad bhāṣya)
12	श्वेताश्वतर उपनिषद् भाष्य (śvetāśvatara bhāṣya)
13	तैत्त्रेय उपनिषद् भाष्य (taittreya upaniṣad bhāṣya)

Next  let us take ब्रह्म सूत्र / शारीरक सूत्र (brahma sūtra / śārīraka sūtra) which is a युक्ति प्रस्थान (yukti prasthāna – logical exposition). A major commentray called शारीरक भाष्य (śārīraka  bhāṣya) on the same, was written by श्री आदि शंकराचर्य (śrī ādi śaṁkarācarya). Interestingly his commentary was further expanded by श्री वाचस्पति मिश्र (śri vācaspati miśra) & श्री  पद्मपाद  (śri padmapāda) independently wrote separate भाष्याणि (bhāṣyāṇi - commentaries) on the same titled भामति (bhāmati) & पञ्चपादिका (pañcapādikā) respectively. श्री अमलानन्द (śri amalānanda) in turn wrote independent भाष्याणि (bhāṣyāṇi- commentaries) called वेदान्तकल्पतरु (vedāntakalpataru) & पञ्चपादिकादर्पण (pañcapādikādarpaṇa) on the भामति (bhāmati) & पञ्चपादिका (pañcapādikā) respectively. The former was further commented by श्री अप्पयदीक्षित (śri appayadīkṣita) in his परिमल (parimala) while the श्री प्रकाशात्मन् (śrī prakāśātman) wrote a विवरण (vivaraṇa-gloss) on पञ्चपादिका (pañcapādikā) and so on goes the rich tradition of philosophical commentaries.

For example, Sri R. Thangaswamy in his famous research titled ‘Advaita Vedanta Literature – A Bibleographic Survey”,  has traced a huge corpus of commentaries (close to 50) on the ब्रह्मसूत्र  भाष्य / शारीरक भाष्य (brahmasūtra bhāṣya  / śārīraka  bhāṣya) alone. The same list has been referred by Sri Pulasth Soobah Roodurmun in his famous book called “Bhamati and Vivarana schools of Advaita Vedanta – A Critical Approach”.

Similarly,  for  श्रीमद् भगवद्गीता (śrīmad bhagavadgītā), which is a साधन प्रस्थान (sādhana prasthāna – instrumental source) a comprehensive commentary called श्रीमद् भगवद् गीता शंकर भाष्य (śrīmad bhagavad gītā śaṃkara bhāṣya) has been written by श्री आदि शङ्कराचार्य भगवत्पाद (śrī ādi śaṅkarācārya bhagavatpāda).

Interestingly, श्री आदि शङ्कराचार्य भगवत्पाद (śrī ādi śaṅkarācārya bhagavatpāda) has provided a very detailed cross-referencing scriptural testimonies in his प्रस्थानत्रयभाष्याणि (prasthānatrayabhāṣyāṇi – triple source commentaries) which has been summarized conciely in this table by Sri V. Panoli

    Again, in terms of स्तोत्र स्तुति ग्रन्थाः (stotra stuti granthāḥ - eulogical treatizes) it is believed that devotional mystical renderings of श्री आदि शङ्कराचार्य भगवत्पाद (śrī ādi śaṅkarācārya bhagavatpāda)  include the following.

There are six branches within the same Vedhantha just as there are six ghats in the same river. In these, Ganapathyam lays down the worship of Gailapathi for attaining Moksha. Koumaram prescribes the worship of Kumaraswami (Murugan). Saktham prescribes the worship of Ambal. VaishiJavam is worship of Vishnu and Saivam is worship of Siva. Because AdhiSankara streamlined the methods of worship in these six ways and established them as orthodox he is known as ‘Shanmatha Prathishtapanachariar’. -translation by Sri V. Krishnamachari

    Further, in correspondence with the पञ्चमहावेदयज्ञाः (pañcamahāvedayajñāḥ – five supreme vedic sacrifices) prescribed in the वेदशास्त्र (vedaśāstra – vedic scripture), the परमाचार्य (paramācārya) lays down पञ्चायतनपूजा (pañcāyatanapūjā – five fold worship) to be performed as part of his नित्यकर्मसाधन (nityakarmasādhana – routine obligatory rite) by every able-minded individual during his गृहस्थ आश्रम (gṛhastha āśrama – householder stage).

दर्शनदर्शीक केवलाद्वैतवेदान्तस्य (darśanadarśīka kevalādvaitavedāntasya – philosophy perspective of absolute  non-dualistic final gnosis)

    केवलाद्वैतवेदान्त उत्तरमीमांसादर्शन (kevalādvaitavedānta uttaramīmāṁsādarśana  – absolute non-dualistic final wisdom posterior inquiry philosophy)  is a ancient school of philosophy originally propunded by परमाचार्य श्री गौडपाद (paramācārya śrī gauḍapāda) who was the परमगुरु श्री आदिषंकराचार्यस्य (paramaguru śrī ādiṣaṃkarācāryasya – grand preceptor of shri adishankaracharya). As this school recognises the परब्रह्मन्  (parabrahman – absolute divinity) as the one and only eternal reality - ब्रह्मैव सत्यं (brahmaṁ satyaṁ - divinity is the only reality), it is popularly refered by this name. Etymologically, the term केवलाद्वैत (kevalādvaita – absolute nonduality) is derived from the terms केवल  (kevala  -   exclusive / absolute)  and अद्वैत  (advaita -  non-duality). The main crux of this schools philosophy is explained by जगद्गुरु श्री आदिशंकराचार्य भगवत्पाद (jagadguru śrī ādiśaṁkarācārya bhagavatpāda) in the following verses from ब्रह्म ज्ञानवलिमाला (brahma jñānavalimālā)  

Original	Transliteration	Translation
ब्रह्म सत्यं जगन्मिथ्या जीवो ब्रह्मैव नापरः। अनेन वेद्यं सच्चास्त्रम् इति वेदान्तडिण्डिमः॥	brahma satyaṁ jaganmithyā jīvo brahmaiva nāparaḥ| anena vedyaṁ saccāstram iti vedāntaḍiṇḍimaḥ||	Brahman is real, the universe is mithyā (it cannot be categorized as either real or unreal). The jiva is Brahman itself and not different. This should be understood as the correct SAstra. This is proclaimed by Vedanta -translated by S.N. Shastry
Sanskrit Reference: ब्रह्म ज्ञानवलिमाला (brahma jñānavalimālā) (20)

    In fact, the revered जगत् गुरु श्री आदिशंकराचार्य भगवत्पाद (jagat guru śrī ādiśaṁkarācārya bhagavatpāda), in the following verses from the beautiful treatise titled आत्मबोधः (ātmabodhaḥ - knwoledge of the self)       

Original	Transliteration	Translation
जगाद्विलक्षणं ब्रह्म ब्रह्मणोऽन्यत्न किंचन। ब्रह्मान्यत् भाति चेत् मिथ्या यथा मरुमरीचिका॥	jagādvilakṣaṇaṁ brahma brahmaṇo'nyatna kiṁcana| brahmānyat bhāti cet mithyā yathā marumarīcikā||	Brahman is counter indicated by the universe; There exists nothing other than Brahman. If anything other than Brahman shines, it must be unreal, just as the unreal image. -translation source Chinmaya Mission

Please be noted that some academic scholars and subject matter experts researching on the historical aspects of केवलाद्वैत शास्त्र साहित्य (kevalādvaita śāstra sāhitya – absolute nondualstic scriptural literature)  are skeptical as to whether the above two works were originally written by श्री आदिशंकराचार्य (śrī ādiśaṁkarācārya) himself or was written much later by some other आचार्य (ācārya - preceptor) belonging to the same lineage.  Even in that case, the fact remains that these works represent the केवलाद्वैत संप्रदाय (kevalādvaita saṃpradāya – absolute non-dualistic tradition).

Moreover, even if we give the benefit fo doubt to the claims of these scholars and discount the factor it was श्री आदिशंकराचार्य (śrī ādiśaṁkarācārya) who initiated the popular dictum “ब्रह्म सत्यं जगन्मिथ्या (brahma satyaṁ jaganmithyā - brahman is real, the universe is false)” highlighting the illusoriness underlying all phenomenal manifestations, there are various other direct and indirect references of similar idea shared by him in some of his प्रस्थानत्रयी भाष्याणि (prasthānatrayī bhāṣyāṇi – triple source commentaries).  For example, in his famous शारीरक भाष्य (śārīraka bhāṣya – corporeal commentary) on the बाद्रायण ब्रह्मसूत्र (bādrāyaṇa brahmasūtra) he unequivocally declares thus:

Original	Transliteration	Translation
समस्तस्य प्रपञ्चस्य मायामात्रत्वम् ।	samastasya prapañcasya māyāmātratvam	The whole phenomenal world is wholly illusory. -translation by self
Sanskrit Reference: शारीरक भाष्य (śārīraka bhāṣya) (3.2.4)

Thus, according to केवलाद्वैतवेदान्त उत्तरमीमांसादर्शन (kevalādvaitavedānta uttaramīmāṁsādarśana  – absolute non-dualistic final wisdom posterior inquiry philosophy), the supreme परब्रह्म (parabrahma – absolute divinity) is essentially an absolute singularity निर्गुण (nirguṇa – beyond attributes) and निराकर (nirākara – without form). However, the स्वरूपलक्षणब्रह्मनस्य (svarūpalakṣaṇabrahmanasya – inherent nature of divinity) is an inseparable mix of सत्यं (satyaṃ- existence), ज्ञानं (jñānaṃ - gnosis) & अनन्तं (anantaṃ - infinity). In other words, the trinity does not mean three different  add-on attributes of ब्रह्मन् (brahman - divinity) but represents the essentail nature of the same.

Although ईश्वर (īśvara - god), is recoginized by केवलाद्वैतवेदान्त उत्तरमीमांसादर्शन (kevalādvaitavedānta uttaramīmāṁsādarśana  – absolute non-dualistic final wisdom posterior inquiry philosophy), yet it is not sectarian in the sense that it does not promote any specific deity like महाविष्णु (mahāviṣṇu) or परमशिव (paramaśiva) in particular. Moreover, even such a ईश्वर (īśvara - god) is considered to be a product of माया (māyā - illusion) and thus निर्गुण ब्रह्मन् (nirguṇa – Divinity beyond attributes) is the one and only कैवल्यसत्त्व  (kaivalyasattva – absolute reality) which is also निम्मित्त उपादान च कारकवत् कारणाः व्यवहारिकसत्त्वस्य (nimmitta upādāna ca kārakavat kāraṇāḥ vyavahārikasattvasya – efficient, material and inctrumental causes of phenomenal realm). To quote Swamy Vivekanandha, a great pattron of advaitic wisdom, “Ishvara is the supreme interpretation of Brahman, the divine Absolute by relative human thought.” Fundamentally, the जीवात्मन् (jīvātman - corporeal soul) is none other than the one and onlyपरमात्मन् (paramātman – supreme soul) who is technically called as ब्रह्मन् (brahman - divinity).  

All kinds of multiplicity and differences in attributes and forms are the product of अविद्यामाया (avidyāmāyā- nescient mystery). Because of the emphasis of the concept of माया (māyā – mystery/illusion) in this school, it is sometimes called as the मायावाद (māyavāda – illusion doctrine) by other schools. Please be noted that अविद्यामाया (avidyāmāyā- nescient mystery) is used here in the sense of अनिर्वचनीय ख्याति (anirvacanīya khyāti - indeterminate cognition) which manifests itself in the following two ways with respect to with respect to अध्यास वाद अविद्या मायायाः (adhyāsa vāda avidyā māyāyāḥ – doctrine of superimposition of nescient mystery).

·        आवरणशक्ति (āvaraṇaśakti – concealing power): It is the तिरस्कार / आवरण शक्ति (tiraskāra / āvaraṇa śakti – concealing force) that encapsulates the  सत्यस्वरूपपरब्रह्मनस्य (satyasvarūpaparabrahmanasya – real nature of supreme divinity). This illustrated by the famous example of the reality of a rope being conceiled by ignorance and

·        विक्षेपशक्ति (vikṣepaśakti – projective power): This is kind of विवर्ताध्यास (vivartādhyāsa – apparent superimposition) that makes the rope to appear as a snake.

 

The next important point to understand is that केवलाद्वैतवेदान्त उत्तरमीमांसादर्शन (kevalādvaitavedānta uttaramīmāṁsādarśana  – absolute non-dualistic final wisdom posterior inquiry philosophy) also advocates एकसत्तावाद / सत्तैक्यवाद (ekasattāvāda / sattaikyavāda – doctrine of single reality / single identity) which is summarized by श्री सुरेश्वराचार्य (śrī sureśvarācārya) in his मानसोल्लास (mānasollāsa)  which is his भाष्य (bhāṣya  - commentary) on the श्री दक्षिनामूर्ति स्तोत्र (śrī dakṣināmūrti stotra) composed by श्री आदि शंकराचार्य भगवत्पाद (śrī ādi śaṃkarācārya bhagavatpāda)  

Original	Transliteration	Translation
जलचन्द्रवेदकस्मिन् निर्भये रज्जुसर्पवत्। प्रतियते यथा स्वर्णे कारणे कटकादिवत्॥ उपात्ते स्यूप्यवच्छुक्तौ व्याप्ते यक्षपुरीव खे। रश्म्यंबुवत्स्फुरद्वपे स्थाणौ चोरवदक्रिये॥ असत्कल्पमिदम् विश्वमात्मन्यारोप्यते भ्रमात्।	jalacandravedakasmin nirbhaye rajjusarpavat। pratiyate yathā svarṇe kāraṇe kaṭakādivat॥ upātte syūpyavacchuktau vyāpte yakṣapurīva khe। raśmyaṃbuvatsphuradvape sthāṇau coravadakriye॥ asatkalpamidam viśvamātmanyāropyate bhramāt।	The one (ātman) appears to be many as one Moon appears to be many in waters, the fearless ātman appears to cause fear like the rope appearing to be a serpent; the cause (ātman) appears to eb the effect like gold appearing to be a bracelet. This Universe which is in reality non-existent, is superimposedm by illusion, in the self-existent (ātman) as silver in the mother-of-pearl, in the all-pervading ātman as a city of Yaksha conjured up in the sky, in the Luminous (ātman), as the mirage appears in the rays of the sun, and in the Immutable (ātman), as the thief in a pillair. -translation by Subbramaniya
Sanskrit Reference: मानसोल्लास (mānasollāsa) (8.28-30)

However, according to the अध्यासवाद अविद्यामायायाः (adhyāsavāda avidyāmāyāyāḥ – doctrine of superimposition of nescient mystery) the आवरणशक्ति (āvaraṇaśakti – concealing power) encapsulates the underlying एकसत्ता (ekasattā – single reality) while the  विक्षेपशक्ति (vikṣepaśakti – projective power) manifests the त्रिस्वभाव सत्त्व (trisvabhāva sattva – triple natured existence). In other words, reality operates in three planes of consciousness listed in the ascending order of their superiority viz.     

 

#	लक्षणसत्त्वस्य (lakṣaṇasattvasya– nature of realm)	Description
A	अनित्यसत्यम् (anityasatyam – transcient truth)
1	प्रातिभासिक सत्त्वं (prātibhāsika sattvaṁ – illusory realm)	The illusory plane of consciousness, like mistaking the rope to be a snake and experiencing the associated fear
2	व्यावहारिक सत्त्वं (vyāvahārika sattvaṁ – empirical realm)	Next comes the  empirical plane of day to day practical consciousness where in one observes and experiences all kinds of multiplicities and varieties in the world
B	नित्यसत्यम् (nityasatyam – eternal truth)
3	पारमार्थिक सत्त्वं (pāramārthika sattvaṁ – ultimate/noumenal realm)	Finally, comes the transcendent plane of absolute consciousness which is the अनेकान्तपरिपूरणकेवलाद्वैतपरब्रह्मन्सच्चिदानन्दम् (anekāntaparipūraṇakevalādvaitaparabrahmansaccidānandam - multivalent holistic absolute nondualistic  existence-consciousness-bliss)

 

Thus, केवलाद्वैतवेदान्त उत्तरमीमांसादर्शन (kevalādvaitavedānta uttaramīmāṁsādarśana  – absolute non-dualistic final wisdom posterior inquiry philosophy) also preaches विवर्तवाद (vivartavāda – apparance doctrine) according to which, the world out there, is technically called as the व्यावहारिक सत्त्वं (vyāvahārika sattvaṁ – empirical realm) is only a अनित्यसत्यम् (anityasatyam – transcient truth) and hence is consdered merely as the विवर्तव्यक्तत्व (vivartavyaktatva – phenomenal manifestation), whereas the  पारमार्थिक सत्त्वं (pāramārthika sattvaṁ – ultimate/noumenal realm) is the one and only नित्यसत्यम् (nityasatyam – eternal truth).    

            The next important point to understand is that over the centuries, the केवलाद्वैतवेदान्त उत्तरमीमांसादर्शन (kevalādvaitavedānta uttaramīmāṁsādarśana  – absolute non-dualistic final wisdom posterior inquiry philosophy) has branched itself into various sub-schools expanding upon the विवर्तवाद (vivartavāda – apparance doctrine) in terms of providing alternate explanations regargin the लक्षणविक्षेपश्कतेः अध्यासस्य (lakṣaṇa vikṣepaśkateḥ adhyāsasya –  nature of the projective power of superimposition)

E	केवलाद्वैत अविभागाद्वैत (kevalādvaita avibhāgādvaita -undifferentiated  absolute nondualism)	श्री वीज्ञानभिक्षु (śrī vījñānabhikṣu)

 

From a epistemological perspective, केवलाद्वैतवेदान्त उत्तरमीमांसादर्शन (kevalādvaitavedānta uttaramīmāṁsādarśana  – absolute non-dualistic final wisdom posterior inquiry philosophy) school recognises all the षड्विधप्रमाणाः ज्ञान्स्य (ṣaḍvidhapramāṇāḥjñānsya – sixfold epistemological mesasures of knowledge) viz.

 

#	प्रमाण (pramāṇa - process of knowing)
1	प्रत्यक्ष (pratyakṣa - perception)
2	अनुमान (anumāna - inference)
3	उप्मान (upmāna - comparision)
4	शब्द (śabda - testimony)
5	अनुपालब्धि (anupālabdhi - non apprehension)
6	अर्थापत्ति (arthāpatti - hypothesis)

 

This fact is testified in the वेदान्तपरिभाषा (vedāntaparibhāśā) which is a famous प्रमाणविद्या प्रकरण (pramāṇavidyā prakaraṇa – epistomology treatise) written byआचार्य श्री धर्मराज अध्वारिन्द्र (ācārya śrī dharmarāja adhvārindra)

Original	Transliteration	Translation
तानि च प्रमाणानि षट् – प्रत्यक्षानुमानो उपमानशब्दार्थापत्त्यनुपलब्धिबेदात्॥	tāni ca pramāṇāni ṣaṭ - pratyakṣānumāno upamānaśabdārthāpattyanupalabdhibedāt॥	Those means of knowledge are six in number, their divisions being perceptions, inference, comparision, verbal testimony, presumption and non-apprehension. -translation by Swamy Madhavanandha (RKM Order)
Sanskrit Reference: वेदान्तपरिभाषा (vedāntaparibhāṣā) (1.9)

But please remember that amongst the षड्विधप्रमाणाः ज्ञान्स्य (ṣaḍvidhapramāṇāḥjñānsya – sixfold epistemological mesasures of knowledge), this school values the शब्दप्रमाणवेदशास्त्रस्य (śabdapramāṇavedaśāstrasya –  testimonial validaion of vedic scripture) as the ultimate authority, particularly when it comes to understanding the पारमार्थिक सत्त्वं (pāramārthika sattvaṁ – ultimate/noumenal realm). Moreover, even there it gives  higher validity to the ज्ञानखाण्डानि वेदसंहिताणाम् (jñānakhāṇḍāni vedasaṃhitāṇām – gnostic sections of the vedic corpuses) rather than the कर्मखाण्डानि वेदसंहिताणाम् (karmakhāṇḍāni vedasaṃhitāṇām – ritual sections of the vedic corpuses).

               From a soteriological perspective, this school believes that sublimation of the sense of individuality bound by माया (māyā - illusion) and absolute unification with the ब्रह्मन् (brahman - divinity) leads to परमुक्ति (paramukti - ultimate salvation). In the words of आदि शंकराचार्य भगवत्पाद (ādi śaṁkarācārya bhagavatpāda),

Original	Transliteration	Translation
वेदान्तसिद्धान्तनिरुक्तिरेषा ब्रह्मैव जीवः सकलं जगच्च। अखण्डरूपस्थितिरेव मोक्षो ब्रह्मद्वितीये श्रुत्यः प्रमाणम्॥	vedāntasiddhāntaniruktireṣā brahmaiva jīvaḥ sakalaṃ jagacca। akhaṇḍarūpasthitireva mokṣo brahmadvitīye śrutyaḥ pramāṇam॥	The final opinion of all the Vedantic discussions, is that the jiva as well as the entire universe are Brahman alone, that liberation means to be rooted in Brahman, the indivisible Entity. The state that Brahman is non dual has its authority in Sruti. -translation by Swamy Chimanayanada
Sanskrit Reference: विवेकचूडामणि (vivekacūḍāmaṇi) (479)

To this end, two modes of emanation are recognized viz. the lower and higher states of spiritual enlightenment depending upon whether the soul realizes the सगुण ब्रह्मन् (saguṇa brahman – divinity with qualities) or the निर्गुण ब्रह्मन्  (nirguṇa brahman – divinity beyond qualities). While the former can attain only क्राम मुक्ति (krāma mukti - gradual liberation) through विदेह मुक्ति (vidheha mukti) by taking the देवयान  (devayāna  -  divine path) to the highest ब्रह्मलोक  (brahmaloka – divine realm), the latter case are previlidged for जीवन्मुक्ति (jīvanmukti – living liberation) by leading a life of renunciation engaged in selfless निश्कामकर्म (niśkāmakarma – desireless service).

Conclusion

 Moreover, in my humble opinion, श्री आदि शङ्कराचार्य भगवत्पाद (śrī ādi śaṅkarācārya bhagavatpāda) also deserves to be called as the Father figure playing the role of the original seed of पवित्र वटवृक्ष वेदान्त दर्शनस्य (pavitra vaṭavṛkṣa vedānta darśanasya - Holy Banyantree of final philosophical wisdom) from which all other branches and even other genetically mutated Vedantic seeds evolved eventually, just as one biological species evolves from another species eventually. For example, the sacred विशिष्टाद्वैतवेदान्तदर्शन (viśiṣṭādvaitavedāntadarśana – qualified non-dualistic final-wisdom philosophy) and the द्वैतवेदान्तदर्शन  (dvaitavedāntadarśana – dualsitic final-wisdom philosophy) are but honorable examples of such philosophical evolution. Although there could be many ideological differences between these schools and the केवलाद्वैतवेदान्तदर्शन (kevalādtvaitavedāntadarśana – absolute non-dualistic final-wisdom philosophy), yet it is an undeniable fact that श्री आदि शङ्कराचार्य भगवत्पाद (śrī ādi śaṅkarācārya bhagavatpāda) has laid the common foundation stone for them as well.

We can compare this with the evolution of modern physics wherein the contribution of one scientists leads to the other. For example, Sir Isaac Newton's revolutionary theories on the laws of mechanics and gravity are his humble learning and respectful deviations from the works of his predecessors like Aristotle, Rene Descartes, Galileo Galilee, and Johannes Kepler etc... In fact, Newton himself acknowledges this when he humbly admits “I have seen farther other men, it is because I have stood on the shoulders of giants”

Similarly, Albert Einstein made his astounding discoveries of Relativistic physics standing on the shoulders of Newton.You might argue that these schools are fundamentally contradicting with each other as one talks about monism, while other qualified monism and the third complete duality. How can we say they have a common ground? Well if you think deeply u can find the common thread tying all these doctrines together. Of course, one may have to deep dive into their philosophies to see the common truth underlying the apparent differences. Here are my two cents for you.

श्री आदि शङ्कराचार्य भगवत्पाद (śrī ādi śaṅkarācārya bhagavatpāda) very carefully worded his school of philosophy as अद्वैत दर्शन (advaita darśana - non-dualistic philosophy) and not as एकत्व दर्शन (ekatva darśana - monistic philosophy). In other words, द्वैत (dvaita - duality) is hidden parameter in the philosophy of अद्वैत (advaita - nonduality) disguised as the अनिर्वचनीयमाया (anirvacanīyamāyā – ineffable /indeterminable mystery) and hence द्वैत (dvaita - duality) and विशिष्टाद्वैत (viśiṣṭādvaita - qualified non duality) are potentially derivable from it. This is a very important point for us to understand and appreciate the genius in श्री आदि शङ्कराचार्य भगवत्पाद (śrī ādi śaṅkarācārya bhagavatpāda).

For example, subsequent to the era of श्री आदि शङ्कराचार्य भगवत्पाद (śrī ādi śaṅkarācārya bhagavatpāda),  the उत्तरमीमांस / वेदान्त दर्शन(uttaramīmāṃsa/vedānta darśana  - posterior inquiry / final wisdom philosophy) nurtured itself int a huge tree  branching into various schools like

#	दर्शनस्य नाम (darśanasya nāma – name of philosophy)	प्रवार्तक परमाचार्य (pravārtaka paramācārya – primary foounding preceptor)
A	केवलाद्वैतदर्शन  (kevalādtvaita darśana – absolute nondualstc philosophy)	श्री आदिशंकराचार्य भगवद्पाद (śrī ādiśaṁkarācārya bhagavadpāda)
B	विशिष्टाद्वैतदर्शन (viśiṣṭādvaita darśana – qualified  nondualistic philosophy)	श्री रामानुजाचार्य (śrī rāmānujācārya)
C	द्वैत दर्शन  (dvaita darśana – dualsitic philosophy)	श्री मद्वचार्य (śrī madvacārya)
D	औपाधिक भेदाभेद दर्शन (aupādhika bhedābheda darśana – different yet non-different philosophy)	श्री भास्कराचार्य (śrī bhāskarācārya)
E	अचिन्त्य भेद अभेद  दर्शन (acintya bheda abheda darśana)	श्रील रूपा गोस्वामि (śrīla rūpā gosvāmi)
F	शुद्धाद्वैत दर्शन (śuddhādvaita darśana – pure nondualstic philosophy)	श्री वल्लभाचार्य (śrī vallabhācārya)
G	स्वभाविक द्वैताद्वैत दर्शन (svabhāvika dvaitādvaita darśana –  dual yet nondualistic philosophy)	श्री निम्बार्काचार्य (śrī nimbārkācārya)

    Thus, on this eventful day of his महा अवतार जयन्ति (mahā avatāra jayanti - sacred incarnation anniversary) I feel blessed in contemplating on his life and contribution to spirituality I offer my humble salutations at his holy feet recollecting the golden verses

My 2 cents on the controversies regarding authorship of विवेकचूडामणिः (vivekacūḍāmaṇiḥ - crest jewel of discrimination)  

 

    While only श्री आदि शंकराचार्य भगवत्पाद (śrī ādi śaṃkarācārya bhagavatpāda) would probably be the final authority on whether he was the author of विवेकचूडामणिः (vivekacūḍāmaṇiḥ - crest jewel of discrimination) (and similar texts under controversy on his authorship). While traditional orthodoxy including the long list of great आचार्य परंपरा (ācārya paraṃparā – preceptor lineage) from the last 2000+ years of पञ्चास्य मठ संप्रदायाः (pañcāsya maṭha saṃpradāyāḥ - fivefold monastic traditions) established by the जगत्गुरु (jagatguru – global preceptor) Himself. This list includes many मुख्य आचार्याः (mukhya ācāryāḥ - chief preceptors) starting from his trusted अनन्तर शिष्याः (anantara śiṣyāḥ - direct disciples) like श्री पद्मपादाचार्य (śrī padmapādācārya) & श्री सुरेश्वराचार्य (śrī sureśvarācārya) etc., upto the more recent ones viz. His Holiness श्री चन्द्रशेखरेन्द्र सरस्वती (śrī candraśekharendra sarasvatī) & श्री चन्द्रशेखर भारति (śrī candraśekhara bhārati) who were lovingly called as the Sage of Kānci, & Sage of Sringeri respectively.

    Let us now ask ourselves, how many of them in this honorable list were actually disputing i.e., were  denying/doubting the authorship of विवेकचूडामणिः (vivekacūḍāmaṇiḥ - crest jewel of discrimination) ascribed to श्री आदि शंकराचार्य भगवत्पाद (śrī ādi śaṃkarācārya bhagavatpāda)?

    Please remember that this long and rich tradition of subject matter experts, were not only upholders of the केवलाद्वैत संप्रदाय (kevalādvaita saṃpradāya – absolute nondualstic tradtion) but were also अनुष्टाण अद्वैतिनः (anuṣṭāṇa advaitinaḥ - practicing nondualists) through their thought, word and deeds. In fact, many of them were ब्रह्मज्ञान जिवन्मुक्ताः (brahmajñāna jivanmuktāḥ - spiritually enlightened living liberates) as testified by their life histories.

    Moreover, the rich tradition of many other eminent मुख्य  अद्वैत आचार्याः (mukhya advaita ācāryāḥ - chief preceptors of nonduality) and their establishments belonging to last two centuries viz. Bhagavān Śrī Ramana Mahaṛṣi (& Ramanāśram), Bhagavān Śrī Rāmakṛṣṇa Paramahaṃsa (Śrī Rāmakṛṣṇa Mission/Mutt) and Swāmi Chinmayānanda (& Chinmayānanda Mission)  etc. have also consistently ascribed the authorship of the text to श्री आदि शंकराचार्य भगवत्पाद (śrī ādi śaṃkarācārya bhagavatpāda).

For example, Bhagavān Śrī Ramana Mahaṛṣi in his famous introductory summary of the text, very clearly states thus: 

“
    Every being in the world yearns to be always happy and free from the taint of sorrow, and desires to get rid of bodily ailments, etc., which are not of its true nature. Further, everyone cherishes the greatest love for himself, and this love is not possible in the absence of happiness. In deep sleep, though devoid of everything, one has the experience of being happy. Yet, due to the ignorance of the real nature of one’s own being, which is happiness itself, people flounder in the vast ocean of material existence, forsaking the right path that leads to happiness, and act under the mistaken belief that the way to be happy consists in obtaining the pleasures of this and the other world. Unfortunately, however, there is no such happiness which has not the taint of sorrow. It is precisely for the purpose of pointing out the straight path to true happiness that Lord Shiva, taking on the guise of Sri Shankaracharya, wrote the commentaries on the Triple Canon [Prasthana Traya] of the Vedanta, which extols the excellence of this bliss; and that he demonstrated it by his own example in life. These commentaries, however, are of little use to those ardent seekers who are intent upon realising the bliss of liberation but have not the scholarship necessary for studying them. It is for such as these that Sri Shankara revealed the essence of the commentaries in this short treatise, The Crown Gem of Discrimination [Vivekachudamani], explaining in detail the points that have to be grasped by those who seek liberation, and thereby directing them to the true and direct path.”

Similarly, His Holiness Swāmi Chinmayānanda unequivocally declares, “

    Vedanta is truly the Science of Life. Sri Shankara, the great interpreter of Vedanta, not only gave us his commentaries on the Upanishads, the Brahma Sutras and the Bhagavad Gita, but also many primary texts which introduce the seeker to the joys of Vedanta. One of the greatest texts he has written as an introduction to Vedanta, is the Viveka Choodamani, which means, ‘The Crest-Jewel of Discrimination.”

    Again, Swami Madhavānanda of RKM order in the foreword of his famous translation has clearly stated 

“Being an original production of Sankara’s genius, the book..” 

    Similarly, श्री चन्द्रशेखर भारति (śrī candraśekhara bhārati) in his famous commentarial work on the sacred text explains 

“In the realm of religion Sri Samkara is a great revivalist…all these stemmed from the philosophy of Advaita which he taught as the central truth of the Upanishads, the Brahma Sutras and the Bhagavad Gita known as Prasthana Traya of Indian Philosophy…The study of these prasthanatraya-bhashyas require profound knowledge of Samskrit and proficiency in Vyakarana, Nyaya and Mimamsa and in Veda adhyayana…But Sri Bhagavatpada realized that not all will be thus qualified. Intending to instruct such persons in the truth of Advaita Vedanta, he wrote what are called as prakarana granthas in verse and prose varying from a single sloka to a thousand. The more important among these are the Satasloki, Sarva Vedanta Sara Sangraha, the Upadesa Sahasri and the Vivekachudamani…”"

    However, authorship of विवेकचूडामणिः (vivekacūḍāmaṇiḥ - crest jewel of discrimination) which has always been traditionally (as testified by above saint-scholars) ascribed to श्री आदि शंकराचार्य भगवत्पाद (śrī ādi śaṃkarācārya bhagavatpāda), has been questioned by some modern day academic scholars and professors (predominantly from Western world) like Daniel Ingalls, Michael Coman, A. J. Alston etc.  Please remember that with all due respects, we should realize that most of these scholars are more academicians rather than practicing saints. So their modus operandi for their speculations regarding the authorship is confined to mortal intellectual means of linguistic, philosophic textual analysis – technically called as अपर विद्या (apara vidyā – mundane  / lower knowledge), (with very few honorable exceptions like His Holiness Śrī Satcitānanda Sarasvatī) unlike the case of those on the other side of the table, wherein the advocates include ब्रह्मज्ञान जिवन्मुक्ताः (brahmajñāna jivanmuktāḥ - spiritually enlightened living liberates).

    As ordinary seekers like many of us take sides one way or the other based on our personal intellectual bias towards one of these postulates. We also take a boolean approach that if we consider प्रस्थानत्रयी भाष्यानि (prasthānatrayī bhāṣyāni – commentaries on triple sources) authored by श्री आदि शंकराचार्य भगवत्पाद (śrī ādi śaṃkarācārya bhagavatpāda) are (seemingly) bordering on ज्ञानमार्ग (jñānamārga – wisdom path) is appears to be inconsistent his other works which seems to be focusing on other मार्गाः (mārgāḥ - paths) viz. विवेकचूडामणिः (vivekacūḍāmaṇiḥ - crest jewel of discrimination), योगसूत्रभाष्य विवरण (yogasūtrabhāṣya vivaraṇa) etc. touching upon topics of समाधि (samādhi - atonement) etc. pertaining to योग मार्ग (yoga mārga – path of communion), श्री सौन्दर्यलहरी (śrī saundaryalaharī), श्री सुब्रह्मण्यभुजङ्गम् (śrī subrahmaṇyabhujaṅgam) etc., touching upon topics pertaining to भक्ति मार्ग (bhakti mārga – path of devotion), कुमालिनी  योग (kuņďalinī yoga - biomagnetic union) etc.

     But IMHO, the inconsistencies are more superficial... as wisdom is an ocean of spiritual continuum. Truth is one. Moreover, we also we have evidence that आचार्याः (ācāryāḥ - preceptors) like आचार्य श्री वाचस्पति मिश्र (ācārya śrī vācaspati miśra) and आचार्य श्री विज्ञानभिक्षु (ācārya śrī vijñānabhikṣu) have written भाष्यानि (bhāṣyāni – commentaries) across multiple seemingly desperate दर्शनानि (darśanāni - philosophies) including न्याय (nyāya), सांख्य (sāṃkhya),योग (yoga) & वेदान्त (vedānta) etc. It is the same आचार्य श्री वाचस्पति मिश्र (ācārya śrī vācaspati miśra) who wrote respective commentaries like तात्पर्यटीका (tātparyaṭīkā), सांख्यतत्त्वकौमुदि (sāṃkhyatattvakaumudi), योग तत्त्व वैशारदि (yoga tattva vaiśāradi), शारीरक भाष्य भामति (śārīraka bhāṣya bhāmati) for each of those schools. Just because these भाष्यानि (bhāṣyāni – commentaries) focus on different दर्शनानि (darśanāni - philosophies), it does not mean, they were not written by the same person – in this case आचार्य श्री वाचस्पति मिश्र (ācārya śrī vācaspati miśra).  

    Moreover, even if we take the huge corpus of अपौरुषेय शब्द (apauruṣeya śabda – superhuman logos) viz. वेद /श्रुति संहित (veda śruti saṃhita – Vedic corpus) including the ऋग् मन्त्र (ṛg mantra), यजुर् मन्त्र (yajur mantra), साम मन्त्र (sāma mantra) & अथर्व मन्त्र (atharva mantra) and their corresponding उपनिषदः (upaniṣadaḥ - upanishads).  In fact, if one looks superficially, even within each उपनिषदः (upaniṣad - upanishad) there could be potential areas of seeming inconsistences between the श्रुति वाक्याः (śruti vākyāḥ - revelatory statements) apparently seeming to favor one वेदान्त दर्शन (vedānta darśana – Vedanta philosophy) say केवलाद्वैत (kevalādvaita – absolute nonduality), over the others viz. विशिष्टाद्वैत (viśiṣṭādvaita – qualified nonduality) and द्वैत (dvaita - duality), or even the other way round. Same logic applies to ब्रह्म सूत्र (brahma sūtra) & श्रीमद् भगवद्गीता (śrīmad bhagavadgītā). Again, in these scriptures, there are sections where भक्ति मार्ग (bhakti mārga – path of devotion) seems to predominate over ज्ञान मार्ग (jñāna mārga – path of knowledge), योग मार्ग (yoga mārga - path of yoga) & कर्म मार्ग (karma mārga – path of servitude). Citing such reasons, can we say these texts are inconsistent? Just because different chapters of श्रीमद् भगवद्गीता (śrīmad bhagavadgītā) give predominance to different मार्गाः (mārgāḥ - paths), can we conclude that it is not the उपदेश (upadeśa - teaching) of the same भगवान् श्री कृष्णपरमात्म (bhagavān śrī kṛṣṇaparamātma) as there are seeming inconsistencies across chapters or can we conclude it cannot be the authored by श्री व्यास महऋषि (śrī vyāsa mahaṛṣi)?

   I think all of us will agree that if we take a holistic deep dive and connect the dots, these superficial inconsistencies will give way to integral synergies. For after-all, the waves of inconsistencies are only at the superficial level and once we deep dive into the depths of the ocean beds, the highs and lows of the waves vanish and sameness prevails.

    In my humble opinion, the same logic applies to the works of our revered saints as well. The main problem is we tend to judge the works of saints also with a Boolean lenses (if 1 it cannot be 0, if 0 it cannot be 1. We assume that if a saint is a ब्रह्म ज्ञानि (brahma jñāni), he cannot be a ब्रह्म योगि (brahma yogi) or a ब्रह्म भक्त (brahma bhakta).  However, life histories of saints have proven otherwise.

    Let us take some recent examples, it was Bhagavān Śrī Ramana Mahaṛṣi who has given us highest form of ज्ञानमार्ग उपदेश (jñānamārga upadeśa – teaching of wisdom path) through his நான் யார் (nān yār - Who Am I)?” and உள்ளது நாற்பது (uḻḻadu nārpadu – forty verses of reality). At the same time, it is the same Bhagavān Śrī Ramana Mahaṛṣi who blessed us with his mystical outpourings of highest devotional trance through his poems like the அக்ஷரமணமாலை (akṣaramaṇamālai  - Marital Garland of Letters). Again, it is the same Bhagavān Śrī Ramana Mahaṛṣi who gave discourses on योग (yoga), ध्यान (dhyāna) & समाधि  (samādhi).

 Similarly, Bhagavān Śrī Rāmakṛṣṇa Paramahaṃsa considered to be one of the greatest अद्वैतिन् (advaitin - nondualist) in recent times, was also a परम भक्त (parama bhakta – supreme devotee) of देवी श्री काली (devī śrī kālī) and was a seamless practitioner of सादनाः (sādanāḥ - techniques) pertaining to तन्त्र (tantra – tantra), योग (yoga – yoga) as well as वेदान्त (vedānta – vedanta). Again, Swami Vivekananda, his chief disciple, was also an accomplished ज्ञानिन् (jñānin – enlightened one) & योगिन् (yogin – yogi) and has written in detail about all the चतुर् मार्गाः (catur mārgāḥ - four paths).

    Hence, from these testimonies, it is clear that, works of saints are not based on a general boolean algorithm but rather are based on quantum computing algorithms (superposition values). Just because one observes that there are seeming inconsistencies across the different works of a saint, we cannot jump to the conclusion that these texts are not the works of the saint. The inconsistencies observed are only superficial and once we deep-dive, we can connect the dots and appreciate the holistic picture.

    All the मार्गाः (mārgāḥ - paths) are not watertight Boolean compartments (variables) but rather are like quantum computing variables where more than one value can be superimposed simultaneously (1 & 0 can co-exist). In fact, that is the very essence of South Indian temple architectural symbology wherein every temple has चतुर् द्वाराः (catur dvārāḥ - four gates) corresponding to चतुर् मार्गाः (catur mārgāḥ - four paths) and from the perspective of मूल विग्रह (mūla vigraha – presiding deity) all paths are same
