Ahura Mazda (;) (also known as Ohrmazd, Ahuramazda, Hourmazd, Hormazd, Harzoo and Hurmuz, Lord or simply as spirit) is the Avestan name for the creator and sole God of Zoroastrianism, the old Iranian religion predating Islam. Ahura Mazda is described as the highest spirit of worship in Zoroastrianism, along with being the first and most frequently invoked spirit in the Yasna. The literal meaning of the word Ahura is "mighty" or "lord" and Mazda is wisdom. Zoroastrianism revolves around three basic tenets – Good Thoughts, Good Words and Good Deeds.
