In Zoroastrian tradition, life is a temporary state in which a mortal is expected to actively participate in the continuing battle between Asha and Druj. Prior to being born, the "urvan" (soul) of an individual is still united with its "fravashi" (personal/higher spirit), which has existed since Ahura Mazda created the universe. The fravashi before the urvan's split act as aids in the maintenance of creation with Ahura Mazda. During life, the fravashi act as aspirational concepts, spiritual protectors, and the fravashi of bloodline, cultural, and spiritual ancestors and heroes are venerated and can be called upon for aid. On the fourth day after death, the urvan is reunited with its fravashi, in which the experiences of life in the material world are collected for the continuing battle in the spiritual world. For the most part, Zoroastrianism does not have a notion of reincarnation, at least not until the Frashokereti. Followers of Ilm-e-Kshnoom in India believe in reincarnation and practice vegetarianism, among other currently non-traditional opinions, although there have been various theological statements supporting vegetarianism in Zoroastrianism's history and claims that Zoroaster was vegetarian.
