"The alternative view of human nature may be termed dualistic. It conceives of the individual person as comprising an inner essential self or soul, which is nonmaterial, and a physical body. In many religions] based on this view of human nature, the soul is regarded as being essentially immortal and as existing before the body was formed. Its incarnation in the body is interpreted as a penalty incurred for some primordial sin or error. At death the soul leaves the body, and its subsequent fate is determined by the manner in which it has fulfilled what the particular religion concerned has prescribed for the achievement of salvation. This view of human nature and destiny finds most notable expression in Hinduism and, in a subtly qualified sense, in Buddhism; it was also taught in such mystical cults and philosophies of the Greco-Roman world as Orphism (an ancient Greek mystical movement with a significant emphasis on death), Gnosticism (an early system of thought that viewed spirit as good and matter as evil), Hermeticism (a Hellenistic esoteric, occultic movement), and Manichaeism (a system of thought founded by Mani in ancient Iran)."
