Ādi Śaṅkara

c. 8th century CE · Advaita Vedānta · Medieval

Adi Sankara was a philosopher-renunciant of the early medieval period, traditionally placed in the eighth century, who became the central classical interpreter of non-dual Vedanta. His securely discussed work is commentary: on the Brahma-sutra, on the principal Upanishads, and on the Bhagavad Gita, reading those texts as teaching that the deepest self is not other than Brahman.

The world of many things is not dismissed as a casual mistake. It is treated as dependent appearance, not as ultimate reality. A large later literature is hung on his name, including summary verses that state the doctrine in a single breath. Those verses are useful as school capsules and unsafe as quotations. He is also credited with organising monastic centres, a story mixed with hagiography that should not be asked to carry the philosophy.

English readers usually meet him through translations of the commentaries or through modern Advaita presentations that smooth him into a mindfulness teacher. The philosophy is metaphysical. It is about what is finally real, not about a technique for a calmer commute.

Two sentences from the introductory section of the Brahma Sutra commentary are included in Thibaut's English. The famous three-part verse stays Questionable. The commentaries do not yield a stack of further short English mottoes.

Key ideas

  • Non-difference

    The individual self, at the deepest level, is not other than Brahman.

  • Dependent appearance

    The world of many things is not ultimately real in the way it presents itself, which is not the same as calling ordinary life a simple error.

  • Commentary as philosophy

    The arguments live in readings of the Upanishads and the Brahma-sutra, not in a later one-verse summary.

Major works

  • Brahma-sutra commentary (c. 8th century)

    The central systematic work of Advaita, reading the sutras as teaching non-dual Brahman.

  • Upanishad commentaries (c. 8th century)

    Close readings of the principal Upanishads. Attribution of some smaller works is disputed.

  • Bhagavad Gita commentary (c. 8th century)

    A non-dual reading of the Gita, widely studied and not identical with later devotional readings.

Influences

  • The Upanishads
  • Gaudapada
  • Badarayana

Influenced

  • Later Advaita tradition
  • Vivekananda

Common misreadings

  • The one-verse summary that Brahman is real and the world is illusion is a sentence from his pen.
  • Non-duality is a relaxation method rather than a claim about what exists.

Famous lines Ādi Śaṅkara never said

Misattributed means the library does not treat the sentence as theirs. Questionable means there is a real doubt, which is not the same as a proof they never wrote it. Both are listed here.
