Dualism (Indian philosophy)
Another form of dualism in Hindu philosophy is found in the Dvaita ("dualism") Vedanta school, which regards God and the world as two realities with distinct essences; this is a form of theistic dualism. By contrast, schools such as Advaita ("nondualism") Vedanta embrace absolute monism and regard dualism as an illusion ("maya").
Nondualism
Nondualism in Buddhism is explicitly represented by the concept of Buddha-nature, and Tibetan concepts like rigpa and shentong. It has its roots in Buddhist ideas of luminous mind, the "pure" consciousness which shines through when purified from the defilements of hatred, anger and ignorance. Nondualism can also be found in Yogacara thought, and its concept of the alaija-vijnana. Subsequently, combinations of Buddha-nature thought and Yogacara, and also of Yogacara and Madhyamaka, developed in India, Tibet and China, and can be found in Tibetan Buddhism and Zen.
