Özet:

"Dulism", one of the basic characteristics of the Zerdüşt belief system, is based on two opposition powers that play an effective role in the universe. The ancient Aryans believe in the existence of two opposite powers in the universe, named "asha: truth" and "sustainability: lies". This form of faith is among the foundations of faith adopted and spread by Zerdüşt beliefs and religious men. As far as it is clear from Zerdüşt’s sacred texts, Zerdüşt himself has taken into account this faith in his divinity because he knows that there are dual-based beliefs in his beliefs that his interlocutors have received as a target mass, and that there are dual-based beliefs that the opposite spirit beliefs contain, and that they are well aware of some myths. In the history of Iranian mythology, there are many developments and mythological stories that arise from the dualism. Many of the angels and giants in the Iranian mythology are the followers of Iszed or Ehrimen. These are first the good and evil images that exist as a number of moral qualities, and then in the world of existence, and which come into one of the forms of an angel or devil by gaining one personality.
