The Monad produces from his thought a feminine divine entity or principle named Barbelo. She is described as “the first thought”, and the “image” of the Monad. While Barbelo is always referred to as a ‘she’, she is also described as both the primordial mother and father. She is also regarded as “the first man” and described in various terms of androgyny. She is the first of a class of beings referred to as the Aeons, and an exchange between herself and the Monad brings the other Aeons into being. Additionally, the properties of Light and Mind are born from the Monad's reflection on Barbelo. Light is synonymous with Christ, also called “Christ the Autogenes”. The Light and the Mind engage in further creative activity, aided by and glorifying the superior principles of Barbelo and the Monad. Together, they bring forth further Aeons and powers.
