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").
Kabbalah
Although Kabbalah propounds the Unity of God, one of the most serious and sustained criticisms is that it may lead away from monotheism, and instead promote dualism, the belief that there is a supernatural counterpart to God. The dualistic system holds that there is a good power versus an evil power. There are two primary models of Gnostic-dualistic cosmology: the first, which goes back to Zoroastrianism, believes creation is ontologically divided between good and evil forces; the second, found largely in Greco-Roman metaphysics like Neo-Platonism, argues that the universe knew a primordial harmony, but that a cosmic disruption yielded a second, evil dimension to reality. This second model influenced the cosmology of the Kabbalah.
