This introduction to Zoroastrianism assumes no prior knowledge of the faith. The book sets out clearly and succinctly the major beliefs and practices which inform Zoroastrianism today. Zoroastrianism is presented as a living faith, with a coherent and remarkably persuasive theology of good thoughts, good words and good deeds. Contents include: -- The emergence of Zoroastrianism and the dating problem. -- Zarathustra's highly original vision of God and humanity; humanity's relationship with God; the problem of dualism vs. monotheism. -- The mystery of the origin of the religion. -- The adversarial spirit (Angrya Mainyr), and Zoroastrian scriptures. -- How Zoroastrianism bridges the gap between the Indian religion of ancient times, and the later western religions of Judaism, Christianity and Islam. How its prophet anticipates developments in both these families of religions. -- The clash with 19th-century missionaries. -- Contemporary issues and controversies, such as conversion and intermarriage.
