Nonduality

Where does “you” stop and the world begin?

What it is

Nonduality names a family of contemplative traditions that question the split between subject and object. Advaita Vedanta, several schools of Buddhism and Zen approach it through practice rather than argument: look closely at experience and see whether a separate self is actually found.

It is a claim about how experience is structured, not a scientific finding. This site presents it as a tradition to understand and test in attention, not as established fact.

Ideas to carry

  1. 1

    Not two

    Advaita means “not two”: the claim that self and world are not ultimately separate.

  2. 2

    Look for the looker

    Many practices ask you to find the one who is seeing, and to notice what you actually find.

  3. 3

    Practice over belief

    These traditions tend to say: do not believe it, test it in attention.

Established What we know

  1. Advaita Vedanta, the non-dual school of Vedanta, is most associated with the 8th-century teacher Śaṅkara.[1]
  2. Zen grew out of Chinese Chan Buddhism and became established in Japan from the late 12th and 13th centuries.[2]

Interpretation The older lens · Upanishads

The Chandogya Upanishad’s “tat tvam asi”, you are that, compresses nonduality into three words.
