Dualism” The philosophical and religious principle of dualism holds that there are two eternal opposing principles. These can be the opposing principles of Day/Light and Night/Dark and; good and evil, body and spirit, Yin and Yang etc. Zoroastrianism, (Parsism) among other religions, had a principle of good and evil and consequently became archived under Dualism. Noted should be however, that both Ahriman and Ormazd Ahura Mazda) were sons of Zurvan Akarana, who had vowed that the firstborn should reign as king. Ahriman thus ripped open his mother's womb, and Zurvan pronounced that he should rule only for nine thousand years, after which period his twin brother should reign in his place. This shows that the term Dualism does not comply to Zoroastrianism, since the god of evil is to be defeated by the god of Light. All this leads back to Enlil and Enki who were sons of Holy An, literally; the Holy Spirit. In Christianity it points to Jesus defeating Satan.
