Chapter IX.—How Demons Get Power Over Men.

"Since, on the other hand, you are oppressed by strange sufferings inflicted by demons, on your removal from the body you shall have your souls also punished for ever; not indeed by God's inflicting vengeance, but because such is the judgment of evil deeds. For the demons, having power by means of the food given to them, are admitted into your bodies by your own hands; and lying hid there for a long time, they become blended with your souls. And through the carelessness of those who think not, or even wish not, to help themselves, upon the dissolution of their bodies, their souls being united to the demon, are of necessity borne by it into whatever places it pleases. And what is most terrible of all, when at the end of all things the demon is first consigned to the purifying fire, the soul which is mixed with it is under the necessity of being horribly punished, and the demon of being pleased. For the soul, being made of light, and not capable of bearing the heterogeneous flame of fire, is tortured; but the demon, being in the substance of his own kind, is greatly pleased, becoming the strong chain of the soul that he has swallowed up.
