Ahura Mazda

Ahura Mazda () is the Avestan language name for a divinity exalted by Zoroaster as the one uncreated Creator, hence God.The Zoroastrian faith is thus described by its adherents as Mazdayasna, the worship of Mazda. In the Avesta, "Ahura Mazda is the highest object of worship", the first and most frequently invoked divinity in the Yasna liturgy. In Zoroastrian cosmogony and tradition, all the lesser divinities are also creations of Mazda. (eg Bundahishn III)

[Persian] In Persian belief, Ahura Mazdah ("Lord Wisdom") was the supreme god, he who created the heavens and the Earth, and another son of Zurvan. Atar, his son, battled Azhi Dahaka, the great dragon of the sky, and bound it in chains on a high mountain. The dragon was, however, destined to escape and destroy a third of mankind at the final reckoning, before it was slain. Ahura Mazdah was the god of prophetic revelation, and bore both Ahriman and Ormazd. As leader of the Heavenly Host, the Amesha Spentas, he battles Ahriman and his followers to rid the world of evil, darkness and deceit. His symbol is the winged disc.

Ahura-Mazda (Avestan) Aura-Mazda (Old Persian) Auhr-Mazd (Pahlavi) Hormazd, Hormoz, Ormazd, Ormuzd (Persian) [from Avestan ahura lord of life from the verbal root ahu conscious life + mazda the creator of mind, remembering, bearing in mind from the verbal root man to think + da the creator, bestower; cf Pahlavi dehesh creation] The lord of life and creator of mind; the immutable light, the uncreated supreme deity of the Mazdean system. Pythagoras said that "the Iranian Magis consider Ahura Mazda a being whose body is of light and his soul is of truth." He is referred to as the maker of the material world and father of the six Amesha-Spentas. In later Persian literature similar descriptions of the supreme creator have been given. Ferdowsi refers to him as the lord of jan (consciousness) and kherad (intellect).
Regarding the dualistic cosmic system of the Zoroastrians -- good and evil -- Blavatsky comments: "No more philosophically profound, no grander or more graphic and suggestive type exists among the allegories of the World-religions than that of the two Brother-Powers of the Mazdean religion, called Ahura Mazda and Angra Mainyu, better known in their modernized form of Ormuzd and Ahriman. Of these two emanations, 'Sons of Boundless Time' -- Zeruana-Akrana -- itself issued from the Supreme and Unknowable Principle, the one is the embodiment of 'Good Thought' (Vohu-Mano), the other of 'Evil Thought' (Ako-Mano). The 'King of Light' or Ahura Mazda, emanates from Primordial Light and forms or creates by means of the 'Word,' Honover (Ahuna-Vairya), a pure and holy world. But Angra Mainyu, though born as pure as his elder brother, becomes jealous of him, and mars everything in the Universe, as on the earth, creating Sin and Evil wherever he goes.
"The two Powers are inseparable on our present plane and at this stage of evolution, and would be meaningless, one without the other. They are, therefore, the two opposite poles of the One Manifested Creative Power, whether the latter is viewed as a Universal Cosmic Force which builds worlds, or under its anthropomorphic aspect, when its vehicle is thinking man" (BCW 13:123-4).
Because Maz or Mez in the word Mazda can also be another way of pronouncing myth, Mazda can mean that which is created by Mez, by the hidden truth. Then Ahura-Mazda would mean the life-bearer who is created by the hidden truth.
