Sanskrit expression
Neti Neti (Sanskrit : नेति नेति) is a Sanskrit expression which means "not this, not that", or "neither this, nor that" (neti is sandhi from na iti "not so"). It is found in the Upanishads and the Avadhuta Gita and constitutes an analytical meditation helping a person to understand the nature of Brahman by negating everything that is not Brahman. One of the key elements of Jnana Yoga practice is often a "neti neti search." The purpose of the exercise is to negate all objects of consciousness, including thoughts and the mind, and to realize non-dual awareness.
