Editing Ahriman (section)

===In the Younger Avesta===
''Yasna'' 19.15 recalls that Ahura Mazda's recital of the [[Ahuna Vairya]] invocation puts Angra Mainyu in a stupor. In ''Yasna'' 9.8, Angra Mainyu creates [[Zahhak|Aži Dahaka]], but the serpent recoils at the sight of [[Mithra]]'s mace (''[[Yasht]]'' 10.97, 10.134). In ''[[Yasht]]'' 13, the [[Fravashi]]s defuse Angra Mainyu's plans to dry up the earth, and in ''Yasht'' 8.44 Angra Mainyu battles but cannot defeat [[Tishtrya]] and so prevent the rains. In ''[[Vendidad]]'' 19, Angra Mainyu urges Zoroaster to turn from the good religion by promising him sovereignty of the world. On being rejected, Angra Mainyu assails Zoroaster with legions of demons, but Zoroaster deflects them all. In ''Yasht'' 19.96, a verse that reflects a Gathic injunction, Angra Mainyu will be vanquished and Ahura Mazda will ultimately prevail.

In ''Yasht'' 19.46ff, Angra Mainyu and Spenta Mainyu battle for possession of ''[[Khvarenah|khvaraenah]]'', "divine glory" or "fortune". In some verses of the Yasna (e.g. ''Yasna'' 57.17), the two principles are said to have created the world, which seems to contradict the Gathic principle that declares Ahura Mazda to be the sole creator and which is reiterated in the cosmogony of ''[[Vendidad]]'' 1. In that first chapter, which is the basis for the 9th–12th-century ''[[Bundahishn]]'', the creation of sixteen lands by Ahura Mazda is countered by the Angra Mainyu's creation of sixteen scourges such as winter, sickness, and vice. "This shift in the position of Ahura Mazda, his total assimilation to this Bounteous Spirit [Mazda's instrument of creation], must have taken place in the 4th century BC at the latest; for it is reflected in [[Aristotle]]'s testimony, which confronts Areimanios with Oromazdes (apud Diogenes Laertius, 1.2.6)."<ref name="JDG_1982_670_673" />

''Yasht'' 15.43 assigns Angra Mainyu to the nether world, a world of darkness. So also ''Vendidad '' 19.47, but other passages in the same chapter (19.1 and 19.44) have him dwelling in the region of the ''daeva''s, which the ''Vendidad'' asserts is in the north. There (19.1, 19.43–44), Angra Mainyu is the ''daevanam daevo'', "''daeva'' of ''daeva''s" or chief of the ''daeva''s. The superlative ''daevo.taema'' is however assigned to the demon Paitisha ("opponent"). In an enumeration of the ''daeva''s in Vendidad 1.43, Angra Mainyu appears first and Paitisha appears last. "Nowhere is Angra Mainyu said to be the creator of the ''daeva''s or their father."<ref name="JDG_1982_670_673" />
