琐罗亚斯德教与祆教(Zoroastrianism and Parsiism)
伊斯兰教出现之前古代伊朗的主要宗教。创始於6世纪。反对多神论，只崇拜最高神阿胡拉.玛兹达。琐罗亚斯德教的经典《阿维斯陀》（即《波斯古经》）中，只有《伽泰》（即《神歌》）据说是琐罗亚斯德本人所着。琐罗亚斯德教的伦理教义主要讲如何保持生命而与邪恶抗争。为了保持生命，人必须从事畜牧和农业，而且生儿育女。与邪恶抗争就是与魔鬼和他所统率的活物（包括人与禽兽）战斗。现存於伊朗偏僻地区并盛行於印度境内帕西人中间。在穆斯林统治下，琐罗亚斯德教徒倍受迫害。

Zoroastrianism and Parsiism
Ancient religion that originated in Iran based on the teachings of Zoroaster. Founded in the 6th century BC, it influenced the monotheistic religions Judaism, Christianity, and Islam. It rejects polytheism, accepting only one supreme god, Ahura Mazda. In early Zoroastrianism, the struggle between good and evil was seen as an eternal rivalry between Ahura Mazda's twin sons, Spenta Mainyu (good) and Angra Mainyu (evil). Later Zoroastrian cosmology made the rivalry between Ahura Mazda himself (by then called Ormazd) and Ahriman. This later cosmology identifies four periods of history; the last began with the birth of Zoroaster. Zoroastrian practice includes an initiation ceremony and various rituals of purification intended to ward off evil spirits. Fire worship, a carryover from an earlier religion, survives in the sacred fire that must be kept burning continually and must be fed at least five times a day. The chief ceremony involves a sacrifice of haoma, a sacred liquor, accompanied by recitation of large parts of the Avesta, the primary scripture. Zoroastrianism enjoyed status as an official religion at various times before the advent of Islam, but Zoroastrians were persecuted in the 8th-10th century, and some left Iran to settle in India. By the 19th century these Indian Zoroastrians, or Parsis, were noted for their wealth and education. The small group of Zoroastrians remaining in Iran are known as the Gabars.
