Adi Shankara

classical teacher of Advaita Vedanta

eighth century CE (traditional dating; exact years debated) · India

Adi Shankara was an Indian philosopher and teacher, traditionally dated to the eighth century CE—the exact years are debated. He is the classical voice of Advaita Vedanta, a Hindu school whose name means “non-dual end of the Vedas.” Advaita teaches that the deepest Self, Atman, and ultimate reality, Brahman, are not two separate things.

He is not the founder of Hinduism, and Advaita is not all of Hinduism. Shankara’s work was to argue, comment, and teach: commentaries on the Upanishads (late Vedic dialogues on self and reality), on the Bhagavad Gita, and on a terse philosophical text called the Brahma Sutras. A work often treated as his own teaching voice is the Upadesasahasri—“A Thousand Teachings.” Later legend adds miracles and a nationwide tour; historians distinguish that story from the commentaries.

Maya, in this school, names the appearance by which one reality is lived as many selves and many objects. It does not mean the world is a cheap trick, or that other people do not matter. The claim is metaphysical: ordinary separation is not the last word about what is. That is not Buddhist not-self, which finds no permanent owner in the stream of experience. It is not Krishna-bhakti as a path of loving a personal Lord. And it is not yet Ramana Maharshi’s later, spare question “Who am I?”—even when Ramana draws on the same vocabulary.

Words used here

Plain meanings for words on this page.

  • Advaita Vedanta

    A school of Hindu philosophy that teaches that the deepest Self and ultimate reality are not fundamentally separate. This view is often called non-duality.

    A little deeper

    “Advaita” means “not two.” Vedanta refers to teachings associated with the later portion of the Vedic tradition, especially the Upanishads. Advaita does not deny ordinary experience; it asks what remains when the sense of separation is examined.

  • Brahman

    In Advaita Vedanta and related Hindu traditions, Brahman names ultimate reality: not a separate object inside the universe, but the fundamental reality of which everything is an expression.

  • Atman

    In many Hindu philosophical contexts, Atman names the deepest Self. In Advaita, this Self is understood as not separate from Brahman.

  • maya

    In Advaita Vedanta, maya names the appearance by which one reality is experienced as a world of many things and many selves. It is not a claim that nothing is happening, and it is not a license to treat other people as fake.

    A little deeper

    Popular speech often hears “illusion” and stops. Classical Advaita is more precise: ordinary experience is not denied; it is asked what it is an appearance of. Other Hindu schools use the word differently.

  • non-duality

    The idea that the separation we normally experience between “me” and “everything else” is not the deepest level of reality.

Where Adi Shankara meets other voices

Adi ShankaraMeister Eckhart

parallel

Oneness is not one doctrine

Both refuse to treat the everyday “me” as the last word about what is most real, and both use language of ground, oneness, and release of grasping.

Both teachers press language until ordinary separation sounds less final. English then says they taught the same thing. They did not. Shankara’s non-duality is Advaita: Atman and Brahman are not two. Eckhart’s intensity is Christian: Godhead, Trinity, the Word born in the soul, a Dominican preacher under later ecclesiastical judgment.

Where they differ

Advaita’s Self is not the Christian soul in relation to a personal God. Eckhart does not teach Brahman. Parallel fire is not a shared metaphysics, and it is not proof that “all mystics agree.”

historical relationship

Classical voice of the school

Advaita Vedanta is older in its roots than one teacher, but Shankara is the classical systematizer through whom the school is most often named: commentaries, argument, and a curriculum of Upanishad, Gita, and Brahma Sutra.
