Description
The Supreme Source: At the center or origin of the pleroma is the unknowable, self-generated Supreme God (the Monad, the One, or the Father).
The Aeons: The pleroma is populated by a hierarchy of divine entities called aeons, which emanate in pairs (syzygies) representing various divine attributes, thoughts, or principles like Mind, Truth, Life, and Wisdom.
The Fall and Creation: According to Gnostic myth, an aeon named Sophia (Wisdom) attempted to emanate on her own without her counterpart, resulting in a flawed, ignorant offspring known as the Demiurge (Yaldabaoth). The Demiurge created the material universe—a dark, flawed realm outside the pleroma.
