If during his earthly pilgrimage a person does not break his connection with evil spirits, he will remain in fellowship with them even after his death, more or less belonging to them, depending upon the degree of intercourse. Unbroken intercourse with fallen spirits consigns one to eternal perdition, while insufficient broken relations render one liable to severe torments on the way to heaven.
