Pre-Islamic Persian religion founded by Zoroaster, and still practised by the Parsees in India. The Zendavesta are the sacred scriptures of the faith. The theology is dualistic, Ahura Mazda or Ormuzd (the good God) being in conflict with Ahriman (the evil God), but the former is assured of eventual victory. The return of Zoroaster will presage the resurrection of the dead and the creation of a paradise on Earth by Ahura Mazda. The free choice of good or evil renders believers responsible for their fate after death in heaven or hell. Procreation and life are valued, but death defiles - hence the custom of exposing corpses to be devoured by vultures. Worship is at altars on which the sacred fire burns.
