12. Human souls rush down here below because they have gazed at their images (in matter) as in the mirror of Bacchus. Nevertheless, they are not separated from their principle, Intelligence. Their intelligence does not descend along with them, so that even if by their feet they touch the earth, their head rises above the sky.[122] They descend all the lower as the body, over which their intermediary part is to watch, has more need of care. But their father Jupiter, pitying their troubles, made their bonds mortal. At certain intervals, he grants them rest, delivering them from the body, so that they may return to inhabit the region where the universal Soul ever dwells, without inclining towards things here below.[123] Indeed what the universe at present possesses suffices it both now and in the future, since its duration is regulated by eternal and immutable reasons, and because, when one period is finished, it again begins to run through another where all the lives are determined in accordance with the ideas.[124] In that way all things here below are subjected to intelligible things, and similarly all is subordinated to a single reason, either in the descent or in the ascension of souls, or in their activities in general. This is proved by the agreement between the universal order and the movements of the souls which by descending here below, conform to this order without depending on it; and perfectly harmonize with the circular movement of heaven. Thus the actions, fortunes and destinies ever are prefigured in the figures formed by the stars.[125] That is the symphony whose sound is so melodious that the ancients expressed it symbolically by musical harmony.[126] Now this could not be the case unless all the actions and experiences of the universe were (well) regulated by reasons which determine its periods, the ranks of souls, their existences, the careers that they accomplish in the intelligible world, or in heaven, or on the earth. The universal Intelligence ever remains above the heaven, and dwelling there entirely, without ever issuing from itself; it radiates into the sense-world by the intermediation of the Soul which, placed beside it, receives the impression of the idea, and transmits it to inferior things, now immutably, and then changeably, but nevertheless in a regulated manner. WHY SOULS TAKE ON DIFFERENT KINDS OF BODIES. Souls do not always descend equally; they descend sometimes lower, sometimes less low, but always in the same kind of beings (among living beings). Each soul enters into the body prepared to receive her, which corresponds to the nature to which the soul has become assimilated by its disposition; for, according as the soul has become similar to the nature of a man or of a brute, she enters into a corresponding body.
