“This doctrine taught that there were two original principles of the universe: Light, the good one; and Darkness, the evil one. These two had been mixed by a cosmic accident, tainting everything except God. Light is characterized by knowledge and feeling, and acts by design and free will, whereas Darkness is ignorant and blind, and acts at random. Mankind’s role in this life was, through good conduct, to release the parts of himself that belonged to Light back to the place of Light and to release the parts of himself that belonged to Darkness back to the place of Darkness.”
