The major beliefs of Zoroastrianism can be found in its principal holy text, the Avesta. This text claims that the highest god and creator, Ahura Mazdā, is engaged in a primeval battle against Angra Mainyu, the Destructive Spirit. Believers anticipate Ahura Mazdā’s eventual victory, after which the followers of Angra Mainyu will suffer before all of humanity experiences eternal bliss.
