Ahania is the Emanation, or female counterpart, of Urizen, Zoas of reason, in William Blake's mythology. She is the representation of pleasure and the desire for intelligence. Although Urizen casts her out as being the manifestation of sin, she is actually an essential component in Blake's system to achieving Divine Wisdom. She is a figure of the goddess of wisdom. It is through her that the sons and daughters of Urizen are born. In the original myth, her son Fuzon rebels against his father and is responsible for separating Urizen and Ahania. In his later version, Ahania is separated from Urizen after he believes that she is sinful.
