(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.

(1) "When the darkness stirred, the light of the spirit appeared to him. When he saw it he was astonished. He did not know that another power was above him. And when he saw that his likeness was dark compared with the spirit, he felt hurt. And in his pain he lifted up, above the height of the members of darkness, his mind, which was the eye of the bitterness of evil. He caused his mind to take shape in a member of the portions of the spirit, thinking that, by staring down at his evil, he would be able to equal the spirit. But he was not able, for he wanted to do an impossible thing, and it did not take place. But in order that the mind of darkness, which is the eye of the bitterness of evil, might not be destroyed, since he was made partially similar, he arose and shone with a fiery light upon all of Hades, that the equality of the faultless light might become apparent. For the spirit benefited from every form of darkness because he appeared in his majesty.

(12) And in his pride he struck and smote himself with darkness and blindness, and made himself a devil, and that he must be, and abide so eternally. ["In God he knew only the Majesty, and not the Word in the centre, which has the fan or casting shovel: He blinded himself with the astringent darkness; for he would needs in flame himself, and rule in the fire over the light, and over the meekness."]

(7) (Then in our coming strife let both her mortal foes be slain.) Let the Wrath-demon of rapine be cast down. Smite ye against the envy (which would plot against our Throne ), O ye who, abiding by the Good Mind, and in accordance with our holy Order, desire to hold that refuge fast, to whose sacred bond the bounteous man belongs. And therefore, O Ahura! (to save Thy struggling saint who toils with changing lot) will I place (that refuge) for him in Thy world.

(14) This I ask Thee, O Ahura! tell me aright; how shall I deliver that Demon-of-the-Lie into the two hands of Thine Order (as he lives in our hosts) to cast her down to death through Thy Mãthras of doctrine, and to send mighty destruction among her evil believers, to keep those deceitful and harsh oppressors from reaching their (fell) aims ?

(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.

(9) An evil teacher (as that leader is), he will destroy (our) doctrines, and by his teachings he will pervert the (true) understanding of life, seizing away (from me) my riches , the choice and real wealth of (Thy) Good Mind. To You and to Asha, O Ahura Mazda! am I therefore crying with the voice of my spirit's (need)!

(2) "But the light, since he possessed great power, knew the abasement of the darkness and his disorder, namely, that the root was not straight. The crookedness of the darkness was lack of perception, namely, the illusion that there is no one above him. And as long as he was able to restrain his evil, he was covered with the water. And he stirred. And the spirit was frightened by the sound. He lifted himself up to his station, and he saw a great, dark water. And he was nauseated. The thought of the spirit stared down; he saw the infinite light. But he was overlooked by the putrid root. And by the will of the great light the dark water separated. The darkness came up wrapped in vile ignorance, and this was in order that the mind might separate from him, because he prided himself in it.

(97) But when he found that he could not effect it, then he kindled himself, intending to do it some other way; and so then the Son of Light became a Son of Darkness; for he himself consumed the power of his sweet water, and made it to be a sour stink. Of the Second Son, Covetousness. [Avarice]

(6) And between these two spirits the Demon-gods (and they who give them worship) can make no righteous choice , since we have beguiled them. As they were questioning and debating in their council the (personified ) Worst Mind approached them that he might be chosen. (They made their fatal decision.) And thereupon they rushed together unto the Demon of Fury, that they might pollute the lives of mortals .
