History of the Advaita Tradition — Timeline

A note on dates. Dating ancient Indian texts and figures is genuinely difficult. Most dates given here carry uncertainty ranges of decades or centuries. Where scholars disagree substantially, the range is noted. The traditional dates given by the Advaita tradition for Śaṅkara (788–820 CE or 509–477 BCE in some traditions) differ from the scholarly consensus. This Codex follows the scholarly consensus as represented in the sources listed above.

The Early Upanishads

c. 800–300 BCE▼

c. 800–600 BCE

Bṛhadāraṇyaka and Chāndogya Upanishads

The two oldest and longest Upanishads. Contain Yājñavalkya's teaching (Bṛhadāraṇyaka) and the Tat Tvam Asi dialogues (Chāndogya). First systematic formulations of Brahman-Ātman identity.

→ Bṛhadāraṇyaka · Chāndogya

c. 600–400 BCE

Taittirīya, Aitareya, Kaṭha, Kena, Muṇḍaka Upanishads

The second wave of principal Upanishads. Kaṭha establishes the Nachiketa narrative and śreyas/preyas distinction. Muṇḍaka introduces the parā/aparā vidyā distinction and the two-birds image. Kena poses the witness-ground paradox.

→ Kaṭha · Kena · Muṇḍaka

c. 400–300 BCE

Māṇḍūkya, Praśna, Māṇḍūkya-related texts

The Māṇḍūkya — shortest of the principal Upanishads — establishes the four-state analysis (waking, dream, deep sleep, Turīya) and the Oṃ contemplation. Later becomes the basis of Gauḍapāda's Kārikā.

→ Māṇḍūkya

c. 500–200 BCE

Śvetāśvatara Upaniṣad

Theistic and Sāṃkhya elements combined with Upanishadic non-dualism. Contains the two-birds verse (4.6). Significant for later Śaiva Vedanta and for the tradition's engagement with devotional theism.

c. 200 BCE – 200 CE

Brahmasūtras (Vedāntasūtras)

Attributed to Bādarāyaṇa. 555 aphoristic sūtras systematising the teaching of the Upanishads. Together with the Upanishads and Bhagavad Gītā, constitutes the prasthānatrayī — the three canonical bases of all Vedanta schools. All three schools wrote bhāṣyas on these sūtras.

Pre-Śaṅkara Non-Dual Tradition

c. 200 BCE – 700 CE▼

c. 100 BCE – 100 CE

Bhagavad Gītā

Embedded in the Mahābhārata. Not an Upaniṣad but accepted as smṛti authority for all Vedanta schools. Śaṅkara's commentary on the Gītā is one of his most important works. The Gītā synthesises karma, bhakti, and jñāna within a broadly Vedantic framework.

c. 500 CE (approx.)

Gauḍapāda — Māṇḍūkya Kārikā

The first systematic philosophical commentary on an Upanishad from the non-dual perspective. Four chapters: Āgama (the Upanishad's teaching), Vaitathya (the unreality of the waking and dream worlds), Advaita (non-dualism), and Alātaśānti (quenching of the firebrand). Establishes ajātivāda — the doctrine of non-origination. Śaṅkara's paramaguru (teacher's teacher).

→ Māṇḍūkya

fl. c. 700 CE

Govindapāda

Gauḍapāda's disciple and Śaṅkara's teacher. Almost nothing of his own writing survives, but his transmission of the non-dual tradition to Śaṅkara is documented in the tradition.

Ādi Śaṅkarācārya — The Systematic Architecture

c. 788–820 CE▼

c. 788–820 CE

Ādi Śaṅkarācārya

Born in Kalady, Kerala. Systematised Advaita Vedanta through bhāṣyas on the ten principal Upanishads, the Bhagavad Gītā, and the Brahmasūtras — the three canonical texts. Wrote the Vivekacūḍāmaṇi (authenticated by Hacker and Mayeda) and the Upadeśasāhasrī. Established four major monasteries (maṭhas): Śṛṅgeri (south), Dvārakā (west), Badrī (north), Purī (east). Scholarly consensus dates his life to c. 788–820 CE.

→ Śaṅkarācārya

c. 820–900 CE

Direct disciples — Sureśvara, Padmapāda, Hastāmalaka, Toṭakācārya

Each established or presided over one of the four maṭhas. Sureśvara wrote the Naiṣkarmyasiddhi (defending liberation-by-knowledge alone) and Vārttika commentaries on the Upanishads. Padmapāda wrote the Pañcapādikā (commentary on Śaṅkara's Brahmasūtra introduction).

The Other Vedanta Schools

c. 1000–1300 CE▼

c. 1017–1137 CE

Rāmānuja — Viśiṣṭādvaita

Founded the Viśiṣṭādvaita (qualified non-dualism) school. Wrote the Śrī Bhāṣya (commentary on the Brahmasūtras, opposing Śaṅkara's reading) and the Vedārthasaṃgraha. Holds that Brahman, souls, and the world are real but non-separate — souls and the world are the body of Brahman. Liberation is eternal proximity to Viṣṇu, not identity with Brahman.

→ Three schools compared

c. 1238–1317 CE

Madhvācārya — Dvaita

Founded the Dvaita (dualist) school. Holds five eternal distinctions (pañcabheda): between God and souls, God and matter, souls, souls and matter, and different forms of matter. Liberation is eternal beatific enjoyment of God's presence, not merger. Brahman/Viṣṇu is absolutely independent; all else is dependent.

→ Three schools compared

Later Advaita — Vivaraṇa, Bhāmatī, and Sub-schools

c. 900–1600 CE▼

c. 900–1000 CE

Vācaspati Miśra — Bhāmatī School

Named for his commentary on Śaṅkara's Brahmasūtra Bhāṣya. Founded the Bhāmatī sub-school of Advaita, which locates avidyā (ignorance) in the individual jīva. Distinguished from the Vivaraṇa school on the locus and nature of māyā.

c. 1200 CE

Prakāśātman — Vivaraṇa School

The Vivaraṇa school (named for his commentary on Padmapāda's Pañcapādikā) locates avidyā in Brahman/Īśvara. The two sub-schools debated the locus of māyā and the precise nature of the adhyāsa (superimposition) mechanism for over four centuries.

c. 1500–1600 CE

Sadānanda — Vedāntasāra; Madhusūdana Sarasvatī — Advaitasiddhi

The Vedāntasāra is the most widely used introductory manual to Advaita. The Advaitasiddhi is the major systematic defence of Advaita against Madhva's Dvaita critiques — still in use in traditional study.

Modern Period

c. 1800–present▼

1863–1902

Swami Vivekananda

Disciple of Ramakrishna Paramahaṃsa. Presented Advaita Vedanta to Western audiences at the Parliament of the World's Religions, Chicago, 1893. Founded the Ramakrishna Mission. His reading of Advaita as a universalist practical philosophy shaped much of 20th-century reception of the tradition.

1879–1950

Ramana Maharshi

Taught self-inquiry (ātmavicāra) as the direct path to recognising Brahman-Ātman identity. His method — asking 'who am I?' until the questioner dissolves into the witness — is widely regarded as a direct application of Advaita's nididhyāsana. Settled at Aruṇācala, Tamil Nadu.

1896–1982

Swami Chinmayananda

Founder of the Chinmaya Mission. Made classical Advaita Vedanta accessible to the educated urban Indian audience through systematic camp-based teaching of the Upanishads and Bhagavad Gītā.

1916–2004

Swami Dayananda Saraswati (Arsha Vidya)

Student of Swami Chinmayananda. Systematised a highly structured method of Upanishad teaching that has become the dominant framework for formal Advaita training today: complete word-by-word analysis of the Upanishads over multi-year residential programs.
