The dualistic religious system founded by the Persian prophet
Zarathustra (Zoroaster in Greek) and set forth in the
Avesta in the late 7th or early 6th centuries BCE, teaching the worship of
Ahura Mazda in the context of a universal struggle between the forces of light and of darkness. It is one of the most ancient of living religions and once the faith of the Persian Empire. It is also rooted in ancient Aryan traditions. Today there are less than 200,000 Zoroastrians, mostly in Iran, India, and the West. At the age of 30, Zarathustra was returning with river water for
haoma for spring festival when he had a vision and was taken before Ahura Mazda, The Wise Lord, the supreme creator & his 7 created helpers, the Holy Immortals (
Amesha Spentas) by the Vohu
Manah. Zoroastrianism teaches that Ahura Mazda is the supreme god and all others are subordinate to him. It also teaches that the evil spirit,
Angra Mainyu (Ahriman in Pahlavi) and his demons (daevas) upholds the Lie (druj) instead of Truth (asha). As a result, this creates conflict between humans who follow the Lie (dregvant) and those who uphold the Truth (ashavan).
