In Hindu and Jain philosophy, Atman is the soul in its natural state. Many believe that individual "personal" souls exist as an illusion only, and think of Atman as the all-pervading soul of the universe; the universal life-principle and animator of all organisms, and the world-soul.
By contrast, Jiva[?] is the soul in its human state, in which its freedom is limited by the triple bond of anava[?] (ego), karma (action) and maya_(illusion).
