'Mazda', or rather the Avestan stem-form Mazdā-, nominative Mazdå, reflects Proto-Iranian *Mazdāh(female). It is generally taken to be the proper name of the deity, and like its Sanskrit cognate medhā, means "intelligence" or "wisdom". Both the Avestan and Sanskrit words reflect Proto-Indo-Iranian *mazdhā-, from Proto-Indo-European *mn̩sdʰeh1, literally meaning "placing (*dʰeh1) one's mind (*mn̩-s)", hence "wise".
'Ahura' was originally an adjective meaning ahuric, characterizing a specific Indo-Iranian entity named *asura.[1][2][3] Although traces of this figure are still evident in the oldest texts of both India and Iran,[4] in both cultures the word eventually appears as the epithet of other divinities. There are also speculations by historians today that the term Ahura equated to the Persian variety of the Assyrian God Ashur as the Behistun Inscription referred to the Assyrians as Ahura which can also be noted by the similarities in the depictions between the two Gods.[5]
In the Gathas (Gāθās), the hymns thought to have been composed by Zoroaster himself, the two halves of the name are not necessarily used together, or are used interchangeably, or are used in reverse order. However, in the younger texts of the Avesta, both Ahura and Mazda are integral parts of the name Ahura Mazda, and which are conjoined in other old Iranian languages.
Even though Ahura Mazda was a deity in the Old Iranian religion, he had not yet been given the title of an "uncreated God". This title was given by Zoroaster who proclaimed Ahura Mazda as the uncreated God wholly wise, benevolent and good, as well as the creator and upholder of asha. As Ahura Mazda is described as the creator and upholder of asha, he is a supporter and guardian of justice, and the friend of the just man. Zoroaster stated that Ahura Mazda was not an omnipotent God, but one that could destroy evil eventually.
Zoroaster also spoke of a rival to Ahura Mazda, who was similarly uncreated. This rival was the evil spirit, Angra Mainyu. One of Ahura Mazda's objectives is to destroy Angra Mainyu and create a universe which is completely good. To achieve such a universe, Ahura Mazda initially offered Angra Mainyu peace, which Angra Mainyu refused. Ahura Mazda then set out to establish a spiritual army. One of his first acts was the creation of the seven Amesha Spentas, who were to monitor and protect each of the seven creations.
Zoroaster was born into a religious world worshiping many gods named daevas along with three greater gods, each bearing the title Ahura. Zoroaster proclaimed that only one of these three gods, Ahura Mazda was the sole uncreated creator of the universe. He stated that this source of all goodness was the only Ahura worthy of the highest worship. He further stated that Ahura Mazda created spirits known as yazatas to aid him, who also merited devotion. Zoroaster proclaimed that all of the Iranian daevas were demons and deserved no worship. These demons were created by another uncreated entity, Angra Mainyu, the hostile spirit. The existence of Angra Mainyu was the source of all sin and misery in the universe. Zoroaster claimed that Ahura Mazda was not an omnipotent God, but used the aid of humans in the cosmic struggle against Angra Mainyu. Nonetheless, Ahura Mazda is Angra Mainyu's superior, not his equal. Angra Mainyu and his daevas which attempt to afflict humans away from the path of righteousness would eventually be destroyed. [7]
[edit] Achaemenid Empire
Much about Zoroastrianism as a whole is not known during the Achaemenid period. The representation and invocation of Ahura Mazda can be seen on royal inscriptions written by the Achaemenid kings. The most notable of all the inscriptions is the Behistun Inscription written by Darius I which contain many references to Ahura Mazda. Through most of Darius' reign and till Artaxerxes II, Ahura Mazda is invoked alone as the deity of Zoroastrianism. Under the reign of Artaxerxes II, royal inscriptions stopped the sole invocation of Ahura Mazda and began invoking a triad of divinities, consisting of Ahura Mazda, Mithra, and Anahita. An inscription written in Greek was found in a late “Frātadāra” Achaemenid temple at Persepolis which invoked Ahura Mazda and two other divinites, most likely Mithra and Anahita. On the Elamite Persepolis Fortification Tablet 377, Ahura Mazda is invoked along with Mithra and Voruna (Apam Napat). Artaxerxes III makes this invokation to the three divinities again in his reign. In the early Achaemind period, there are no representations of Ahura Mazda. Previously, the winged symbol with a male figure who was formerly regarded by European scholars Ahura Mazda has been shown to represent the royal xvarənah. However, it was customary for every emperor from Cyrus till Darius III to have an empty chariot drawn by white horses to accompany the Persian army on battles. The use of images of Ahura Mazda began in the western satrapies of the Achaemenid Empire in the late 5th century BCE. Under Artaxerxes II, the first literary reference as well as a statue of Ahura Mazda was built by a Persian governor of Lydia in 365 BCE.
[edit] Parthian Empire
Very little is known about religion during the Parthian Empire due to poor documentation. However, what is known is the reverence for Ahura Mazda, as well as Anahita and Mithra continued with the same traditions during the Achaemenid era. The worship of Ahura Mazda with images is seen in the Parthian era, but is stopped with the beginning of the Sassanid period. Zoroastrian iconoclasm which can be traced to the end of the Parthian period and the beginning of the Sassanid eventually put an end to the use of all images of Ahura Mazda in worship. However, Ahura Mazda remained a dignified male figure, standing or on horseback which is found in Sasanian investiture.
[edit] Sassanid Empire
During the time period of the Sassanid Empire, a heretic form of Zoroastrianism termed Zurvanism had emerged. It enjoyed adherents throughout the Sassanid Empire, most notably the royal lineage of Sassanian emperors. Under the reign of Shapur I, Zurvanism spread and became a widespread cult. In Zurvanism, Ahura Mazda loses the title that Zoroaster had given of an "uncreated creator" and is just one of two twin sons of Zurvan, their father and the primary deity. Zurvanism also makes Ahura Mazda and Angra Mainyu of equal strength and only contrasting divinities. Zurvanism revokes Zoroaster's original message of Ahura Mazda as the uncreated God, and the uncreated creator of all, and reduces Ahura Mazda to a created deity. Other than Zurvanism, the Sassanian kings demonstrated their devotion to Ahura Mazda in other fashions. Five kings took the name Hormizd and Bahram II created the title of "Ohrmazd-mowbad" which was continued after the fall of the Sassanid Empire and through the Islamic times. All devotionial acts in Zoroastrianism which first become known from the Sassanian period begin with homage to Ahura Mazda. The five Gahs begin with the declaration in Middle Persian, that "Ohrmazd is Lord" and incorporate the Gathic verse "Whom, Mazda hast thou appointed my protector). Zoroastrian prayers are to be said the presence of light, either in the form of fire or the sun. In the Iranian dialects of Yidḡa and Munǰī, the sun is still called "ormozd".
[edit] Present-day Zoroastrianism
In 1884, Martin Haug proposed a new interpretation of Yasna 30.3 that subsequently influenced Zoroastrian doctrine to a significant extent. According to Haug's interpretation, the "twin spirits" of 30.3 were Angra Mainyu and Spenta Mainyu, the former being literally the 'Destructive Spirit'[n 1] and the latter being the 'Bounteous Spirit' (of Mazda). Further, in Haug's scheme Angra Mainyu was now not Ahura Mazda's binary opposite, but—like Spenta Mainyu—an emanation of Him. Haug also interpreted the concept of a free will of Yasna 45.9 as an accommodation to explain where Angra Mainyu came from since Ahura Mazda created only good. The free will, so Haug, made it possible for Angra Mainyu to choose to be evil. Although these latter conclusions were not substantiated by Zoroastrian tradition (and are today rejected by the academic community), at the time Haug's interpretation was gratefully accepted by the Parsis of Bombay since it provided a defense against Christian missionary rhetoric,[n 2] particularly the attacks on the Zoroastrian idea of an uncreated Evil that was as uncreated as God was. Following Haug, the Bombay Parsis began to defend themselves in the English language press; the argument being that Angra Mainyu was not Mazda's binary opposite, but Her subordinate, and who—as in Zurvanism also—chose to be evil. Consequently, Haug's theories were disseminated as a Parsi interpretation, also in the West, where they appeared to be corroborating Haug. Reinforcing themselves, Haug's ideas came to be iterated so often that they are today almost universally accepted as doctrine. For a scholastic review of the theological developments in Indian Zoroastrianism, particularly with respect to the devaluation of Angra Mainyu to a position where the (epitome of) pure evil became viewed as a creation of Mazda (and so compromised their figure of pure good), see
In Manichaeism, the name Ohrmazd Bay ("god Ahura Mazda") was used for the primal figure Nāšā Qaḏmāyā, the "original man" and emanation of the Father of Greatness (in Manicheism called Zurvan) through whom after he sacrificed himself to defend the world of light was consumed by the forces of darkness. Although Ormuzd is freed from the world of darkness his "sons" often called his garments or weapons remain. His sons, later known as the World Soul after a series of events will for the most part escape from matter and return again to the world of light where they came from. Manicheans often identified many of Mani's cosmological figures with Zoroastrian ones. This may be in part Mani was born in the greatly Zoroastrian Parthian Empire. However another reason for why this may be is that in Manicheism the religions of Zoroastrianism, Christianity and Buddhism were in fact deviations of the true religion that Mani taught and in a way they were the same religion, hence making it easier to identify the cosmological figures of Mani with the cosmological figures of Zoroastrianism.
In Sogdian Buddhism, Xwrmztʔ (Sogdian was written without a consistent representation of vowels) was the name used for the Buddhist ruler-deity Śakra. Via contacts with Turkic-speaking peoples like the Uyghurs, this Sogdian name came to the Mongols, who still name this deity Qormusta Tengri; Qormusta (or Qormusda) is now a popular enough deity to appear in many contexts that are not explicitly Buddhist.
