Zoroastrianism a panentheistic faith with a transcendent divinity, widely believed to have influenced the theology of the Ismaeli branch of Islam. Other Zoroastrian scholars argue that since Zoroaster’s divinity covers both being and mind as immanent entities, it is better described as a belief in an imminent self-creating universe with consciousness as its special attribute, thereby putting Zoroastranism in the pantheistic fold where it can be easily traced to its shared origin with Indian Brahmanism. In any case, Ahura Mazda’s creation—evident is widely agreed as asha, truth and order—is the antithesis of chaos, which is evident as druj, falsehood and disorder. The resulting conflict involves the entire universe, including humanity, which has an active role to play in the conflict.
The religion states that active participation in life through good deeds is necessary to ensure happiness and to keep chaos at bay. This active participation is a central element in Zoroaster’s concept of free will, and Zoroastrianism rejects all forms of monasticism. Ahura Mazda will ultimately prevail over the evil Angra Mainyu or Ahriman, at which point the universe will undergo a cosmic renovation and time will end. In the final renovation, all of creation—even the souls of the dead that were initially banished to “darkness”—will be reunited in Ahura Mazda, returning to life in the undead form. At the end of time, a savior-figure (a Saoshyant) will bring about a final renovation of the world (frashokereti), in which the dead will be revived.
In Zoroastrian tradition, the “chaotic” is represented by Angra Mainyu (also referred to as “Ahriman”), the “Destructive Principle”, while the benevolent is represented through Ahura Mazda’sSpenta Mainyu, the instrument or “Bounteous Principle” of the act of creation. It is through Spenta Mainyu that transcendental Ahura Mazda is immanent in humankind, and through which the Creator interacts with the world. According to Zoroastrian cosmology, in articulating the Ahuna Vairya formula, Ahura Mazda made His ultimate triumph evident to Angra Mainyu. As expressions and aspects of Creation, Ahura Mazda emanated the Amesha Spentas (“Bounteous Immortals”), that are each the hypostasis and representative of one aspect of that Creation. These Amesha Spenta are in turn assisted by a league of lesser principles, the Yazatas, each “Worthy of Worship” and each again a hypostasis of a moral or physical aspect of creation.
