(43) According to the Persians, there coexisted in eternity two principles. The first of these, Ahura-Mazda, or Ormuzd, was the Spirit of Good. From Ormuzd came forth a number of hierarchies of good and beautiful spirits (angels and archangels). The second of these eternally existing principles was called Ahriman. He was also a pure and beautiful spirit, but he later rebelled against Ormuzd, being jealous of his power. This did not occur, however, until after Ormuzd had created light, for previously Ahriman had not been conscious of the existence of Ormuzd. Because of his jealousy and rebellion, Ahriman became the Spirit of Evil. From himself he individualized a host of destructive creatures to injure Ormuzd.

(44) When Ormuzd created the earth, Ahriman entered into its grosser elements. Whenever Ormuzd did a good deed, Ahriman placed the principle of evil within it. At last when Ormuzd created the human race, Ahriman became incarnate in the lower nature of man so that in each personality the Spirit of Good and the Spirit of Evil struggle for control. For 3,000 years Ormuzd ruled the celestial worlds with light and goodness. Then he created man. For another 3,000 years he ruled man with wisdom, and integrity. Then the power of Ahriman began, and the struggle for the soul of man continues through the next period of 3,000 years. During the fourth period of 3,000 years, the power of Ahriman will be destroyed. Good will return to the world again, evil and death will be vanquished, and at last the Spirit of Evil will bow humbly before the throne of Ormuzd. While Ormuzd and Ahriman are struggling for control of the human soul and for supremacy in Nature, Mithras, God of Intelligence, stands as mediator between the two. Many authors have noted the similarity between mercury and Mithras. As the chemical mercury acts as a solvent (according to alchemists), so Mithras seeks to harmonize the two celestial opposites.

(7) (For He has sovereign control.) He who conceived of these (truths of the Mãthra) as their first (inspirer), (and as He thought their existence they (all) as (His) glorious (conceptions first) clothed themselves in the stars ), He is through His understanding the Creator of the Righteous Order. And thus likewise He supports His Beneficent Mind (in His saints). And these (holy creatures) may’st Thou cause to prosper by Thy Spirit (since they are Thine own), O Ahura Mazda! Thou who art for every hour the same !

(7) Upon this Âramaiti (the personified Piety of the saints) approached, and with her came the Sovereign Power, the Good Mind, and the Righteous Order. And (to the spiritual creations of good and of evil) Âramaiti gave a body, she the abiding and ever strenuous . And for these (Thy people) so let (that body) be (at the last), O Mazda! as it was when Thou camest first with creations !

(2) Aye, (that blessedness, which is the) best (creation) of this most bounteous spirit, Ahura Mazda will bring forth in action with words from the mouth and tongue of His Good Mind (within His seers), and by the two hands of Âramaiti (His Piety as she lives within the soul). And by such wise (beneficence is) He the father of the righteous Order (within our worship and our lives).
