Zoroastrianism is a monotheistic religion founded by Zoroaster that believes in a single god, Ahura Mazda, who represents light, wisdom and goodness. It has a dualistic view of the world where Ahura Mazda is constantly battling the evil spirit Ahriman, who represents darkness and destruction. Followers aim to support Ahura Mazda through good thoughts, words and deeds. Fire is a central symbol as a manifestation of Ahura Mazda's power. The religion divides time into creation, the current mixing of good and evil, and the final victory of good. Zoroastrians today are mainly found in Iran and India.
