To Hindus every person has an essential self or atman. Some view it as the same as Brahman and other as a form of Brahman. The ultimate goal of existence, Hindus believe, is achieving moksha, or union with Brahman. To do that, individuals must free themselves from selfish desires that separate them from Brahman. Most people cannot achieve moksha in one lifetime, but Hindus believe in reincarnation, or the rebirth of the soul in another bodily form. Reincarnation allows people to continue world toward moksha through several lifetimes.
