The Vendidad also merely gives accounts of the dialogues between Ormazd and Zoroaster.
Wise Lord (Ahuro Mazdao - later Ormazd) is the primeval spiritual being, the All-father, who was existent before ever the world arose.
In the Gathas the Good Spirit of Mazda and the Evil Spirit are the two great opposing forces in the world, and Ormazd himself is to a certain extent placed above them both.
Beyond the Lord and his Fire, the Gathas only recognize the archangels and certain ministers of Ormazd, who are, without exception, personifications of abstract ideas.
Thus the Zarvanites represented Ormazd and Ahriman as twin sons proceeding from the fundamental principle of all - Zrvana Akarana, or limitless time.
