From one Soul of the Universe are all Souls derived. . . . Of these Souls there are many changes, some into a more fortunate estate, and some quite contrary. . . . Not all human souls but only the pious ones are divine. Once separated from the body, and after the struggle to acquire piety, which consists in knowing God and injuring none, such a soul becomes all intelligence. The impious soul, however, punishes itself by seeking a human body to enter into, for no other body can receive a human soul; it cannot enter the body of an animal devoid of reason. Divine law preserves the human soul from such infamy. . . . The soul passeth from form to form; and the mansions of her pilgrimage are manifold. Thou puttest off thy bodies as raiment; and as vesture dost thou fold them up. Thou art from old, O Soul of Man; yea, thou art from everlasting."
