Aka Manah is the Avestan language name of Zoroastrianism's demon of the "evil mind" or "evil purpose" or "evil thinking" or "evil intention". Aka Manah is the hypostatic abstraction of accusative akem manah (akәm manah), "manah made evil". Here, manah denotes a state of mind, and akem manah may then be described as the state of mind (or being) that prevents an individual from accomplishing his (moral) duties. The objectification of this malign influence is the demon (daeva) Aka/Akem Manah, who appears in later texts as Middle Persian Akoman and New Persian Akvan.
