Many people say that Satan(Lucifer's Devil side) completely originated from Ahriman. I don't know much about the Avesta of Zoroaster but is that true?
1 Answer
Satan (or the devil) obtained for Jewish ideas almost the same significance as Ahriman for Persian. Indeed, in certain respects he developed greater power than his Persian counterpart, inasmuch as he succeeded in corrupting the immediate followers of God, whereas Ahriman, in his contest with Ahuramazda, did not achieve such success. The Jews tried to preserve the monism that was their original view by explaining the rise of dualism as due to a fall among the originally good spirits.
From AHRIMAN (Angro-mainyush; identical with Satan, the Devil, Armilus)
