It came to pass on a time that matter conceived a desire to attain to the superior region; and when it had arrived there, it admired the brightness and the light which was with God. And, indeed, it wished to seize on for itself the place of pre-eminence, and to remove God from His position. God, moreover, deliberated how to avenge Himself upon matter, but was destitute of the evil necessary to do so, for evil does not exist in the house and abode of God. He sent, therefore, the power which we call the soul into matter, to permeate it entirely. For it will be the death of matter, when at length hereafter this power is separated from it. So, therefore, by the providence of God, the soul was commingled with matter, an unlike thing with an unlike. Now by this commingling the soul has contracted evil, and labours under the same infirmity as matter. For, just as in a corrupted vessel, the contents are oftentimes vitiated in quality, so, also the soul that is in matter suffers some such change, and is deteriorated from its own nature so as to participate in the evil of matter. But God had compassion upon the soul, and sent forth another power, which we call Demiurge, 
that is, the Creator of all things; and when this power had arrived, and taken in hand the creation of the world, it separated from matter as much power as from the commingling had contracted no vice and stain, and hence the sun and moon were first formed; but that which had contracted some slight and moderate stain, this became the stars and the expanse of heaven. Of the matter from which the sun and the moon was separated, part was cast entirely out of the world, and is that fire in which, indeed, there is the power of burning, although in itself it is dark and void of light, being closely similar to night. But in the rest of the elements, both animal and vegetable, in those the divine power is unequally mingled. And therefore the world was made, and in it the sun and moon who preside over the birth and death of things, by separating the divine virtue from matter, and transmitting it to God.
