Plotinos: Complete Works, v. 1 In Chronological Order,...

Here there are two possible faults for the soul. The first consists in the motive that determines her to descend. The second is the evil she commits after having descended here below. The first fault is expiated by the very condition of the soul after she has descended here below. The punishment of the latter fault, if not too serious, is to pass into other bodies more or less promptly according to the judgment delivered about her deserts—and we speak of a "judgment" to show that it is the consequence of the divine law. If however the perversity of the soul passes all measure, she undergoes, under the charge of guardians in charge of her chastisement, the severe punishments she has incurred.
