Vivarta, false superimposition, is a key principle in Vedanta philosophy, the point being that all manifestation/expression covers the formless nature of Reality. Left alone in Its purest state, Brahman is “partless, faultless, actionless, and divine,” to quote the Upanisads. When mentation begins, from the Cosmic Mind on down and out to the collective and individual minds, then does all that is “unreal” obscure the Real. Beings then take what has been projected by the mind, like matter and objects, as being the only reality. That there is more or less of the conscious shine of Brahman in every little thing, while Brahman remains partless and indivisible, this is the lesson of Vivartopadana taught by the Vedanta philosophy.
