Akoman

Aka Manah is the Avestan language name for the Zoroastrian daeva "Evil Mind", "Evil Purpose", "Evil Thinking", or "Evil Intention". Aka Manah also known as Akoman in Middle Persian and Akvan in New Persian, represents the malevolent force of sensual desire that was sent by Ahriman to seduce the prophet Zoroaster. His eternal opponent is Vohu Manah. Aka Manah is the hypostatic abstraction of accusative akem manah, "manah made evil". The objectification of this malign influence is the demon Aka/Akem Manah, who appears in later texts as Middle Persian Akoman and New Persian Akvan.
