The power by which the one appears as many — the world's real-seeming display that veils its single source.
Common misconception
Maya does not mean the world is flatly unreal; it means the world is not what it appears to be on its own.
The question it leaves you holding
If a rope is mistaken for a snake in dim light, was the fear unreal — or only the snake?
Schools that center this concept
Advaita Vedanta — Shankara's non-dualism: only Brahman is real; the individual self is that one Self, mistaking itself as many.
Debates this concept decides
Is the World Real, or Maya? — Is the world solid reality, a passing appearance of Brahman, or a real creation you must take fully seriously? Schools split.
A God With Form, or the Formless Absolute? — Do you worship a personal Lord with qualities, or realize a reality beyond all attributes — and is one higher than the other?
