(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.

(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.

(4) (But e’er these helpers come to me, all rests as yet in gloom.) The evil man is holding back those who are the bearers of the Righteous Order from progress with the Kine, (from progress with the sacred cause) within the region, or the province , he, the evil governor, endowed with evil might , consuming life with evil deeds. Wherefore, whoever hurls him from his power, O Mazda! or from life, stores for the Kine in sacred wisdom shall he make .

(8) And (when the great struggle shall have been fought out which began when the Daêvas first seized the Demon of Wrath as their ally ), and when the (just) vengeance shall have come upon these wretches, then, O Mazda! the Kingdom shall have been gained for Thee by (Thy) Good Mind (within Thy folk). For to those, O living Lord! does (that Good Mind ) utter his command, who will deliver the Demon of the Lie into the two hands of the Righteous Order (as a captive to a destroyer).

(6) In which (last) changing Thou shalt come, and with Thy bounteous spirit, and Thy sovereign power, O Ahura Mazda! by deeds of whom the settlements are furthered through the Righteous Order. And saving regulations likewise unto these shall Âramaiti utter, (she, our Piety within us), yea, (laws) of Thine understanding which no man may deceive .
