Dṛṣṭi-sṛṣṭi-vāda, “perception is creation”, is a strand of Advaita, prominent in the Yoga Vāsiṣṭha, which holds that the world has no existence apart from the mind that perceives it. It contrasts with sṛṣṭi-dṛṣṭi, the common view that the world first exists and is then perceived. It is used to loosen the hold of the world’s apparent solidity.
