Oneness is a spiritual term referring to the 'experience' of the absence of egoic identity boundaries, and, according to some traditions, the perception of an absolute interconnectedness of all matter and thought in space-time, or one's ultimate identity with God (see Tat Tvam Asi). It shares traits with Pantheism. Its meaning may be synonymous to that of nonduality, though some claim that non-duality implies 'not one' and 'not two', i.e. non-duality is analogous to the Hindu formula of negation and to Neti Neti, used in describing the absolute.
