Maya (माया, māyā) is among the most discussed and most misread terms in Sanatan thought. Often translated as "illusion", it does not mean that the world is hallucination or nothing at all. It names the mysterious power by which the one infinite reality appears as the many finite forms — a power neither separate from brahman nor identical with it.
Vedic and Upanishadic Roots
In the Rigveda maya often means a wondrous creative power, especially of the devas; Varuna and Indra are mayin. The Shvetashvatara Upanishad 4.10 makes a metaphysical step: māyāṁ tu prakṛtiṁ vidyāt māyinaṁ tu maheśvaram — "know as prakriti (material nature), and the wielder of as the great Lord". The Bhagavad Gita 7.14 calls daivī, divine, and difficult to cross without surrender to the Lord.
Advaita Reading
In Shankara's Advaita Vedanta, is the principle that makes brahman appear as the world without brahman undergoing real change. This is the doctrine of vivarta — apparent transformation, as a rope appears as a snake in dim light. The snake is not nothing; one really sees it, recoils, trembles. Yet when light is brought, no snake was ever there. So with the world and brahman.
Not Mere Illusion
is described as anirvachaniya — indescribable as either real or unreal. It is not real (sat), because it is sublated by realisation. It is not unreal (asat), because it is experienced. It is therefore mithya, a category of appearance that has practical force without ultimate substantiality.

The cosmic aspect of is sometimes distinguished from its individual aspect, avidya (अविद्या), ignorance. is the universal projecting power; is its presence within an individual mind, by which the atma forgets its identity with brahman and identifies with body and ego. Liberation is the lifting of , by which , while continuing to operate cosmically, no longer binds.
Other Schools
Not every Vedantic school accepts the Advaita reading. Ramanuja rejects the idea of an unreal world and treats material nature as a real mode of brahman. Madhva treats the world as plainly real and distinct from the Lord. Even so, all schools agree that ordinary perception misreads what it sees — taking the dependent as independent, the changing as enduring, the witnessed as the self.
Living with
Practically, the teaching on invites a steady second look. Pleasure and pain, success and loss, name and form — these are real enough to be lived through, but not ultimate enough to be clung to. To see through is not to despise the world but to love it without being deceived by it.
