Zoroastrians believe that there is one universal, transcendent, all-good, and uncreated supreme creator deity, Ahura Mazda, or the "Wise Lord". ("Ahura" meaning "Lord" and "Mazda" meaning "Wisdom" in Avestan). Zoroaster keeps the two attributes separate as two different concepts in most of the Gathas yet sometimes combines them into one form. Zoroaster also claims that Ahura Mazda is omniscient but not omnipotent. In the Gathas, Ahura Mazda is noted as working through emanations known as the Amesha Spenta and with the help of "other ahuras", of which Sraosha is the only one explicitly named of the latter category.
