Ахура Мазда
Ahura Mazda (); is the Avestan name for the creator and sole God of Zoroastrianism. The literal meaning of the word "" is "mighty" or "lord" and " " is "wisdom". Zoroaster, the founder of Zoroastrianism, taught that Ahura Mazda is the most powerful being in all of the existence and the only deity who is worthy of the highest veneration. Nonetheless, Ahura Mazda is not omnipotent because his evil twin brother Angra Mainyu is nearly as powerful as him. Zoroaster taught that the "daevas" were evil spirits created by Angra Mainyu to sow evil in the world and that all people must choose between the goodness of Ahura Mazda and the evil of Angra Mainyu. According to Zoroaster, Ahura Mazda will eventually defeat Angra Mainyu and good will triumph over evil once and for all. Ahura Mazda was the most important deity in the ancient Achaemenid Empire. He was originally represented anthropomorphically, but, by the end of the Sasanian Empire, Zoroastrianism had become fully aniconic.
