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
A modern strand of thought sees "nondual consciousness" as a universal psychological state, which is a common stratum and of the same essence in different spiritual traditions. It is derived from Neo-Vedanta and neo-Advaita, but has historical roots in neo-Platonism, Western esotericism, and Perennialism. The idea of nondual consciousness as "the central essence" is a universalistic and perennialist idea, which is part of a modern mutual exchange and synthesis of ideas between western spiritual and esoteric traditions and Asian religious revival and reform movements.
