Zoroastrianism is a dualist faith that originated in Persia, and over the years it has influenced a number of other faiths. Even though we may not recognize it today, it has been an influence on a number of world religions, especially on Christianity and Islam. Zoroastrianism is a belief system that stresses how we as human beings were meant to strive for our full potential. A primary tenet of the faith is that righteous and upstanding people will participate in the rewards of paradise, while the evil-doers will undergo punishments in hell.
