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").
Ethical dualism
Dualism is a theory which interprets any given situation in terms of two contrasting elements, which from a metaphysical point of view comes to imply that reality consists of two fundamental types of existence which cannot be reduced to each other. Examples of metaphysical dualisms are those between spirit and matter, God and the world, or, as theorized by Descartes, between thought and extension.
