As to the relation between the Supreme Being and man, the soul is a portion or particle of that all-pervading principle, the Universal Intellect or Soul of the World, detached for a while from its primitive source, and placed in connexion with the bodily frame, but destined by an inevitable necessity sooner or later to be restored and rejoined--as inevitably as rivers run back to be lost in the ocean from which they arose. "That Spirit," says Varuna to his son, "from which all created beings proceed, in which, having proceeded, they live, toward which they tend, and in which they are at last absorbed, that Spirit study to know: it is the Great One." Since a multitude of moral considerations assure us of the existence of evil in the world, and since it is not possible for so holy a thing as the spirit of man to be exposed thereto without undergoing contamination, it comes to pass that an unfitness may be contracted for its rejoining the infinitely pure essence from which it was derived, and hence arises the necessity of its undergoing a course of purification. And as the life of man is often too short to afford the needful opportunity, and, indeed, its events, in many instances, tend rather to increase than to diminish the stain, the season of purification is prolonged by perpetuating a connexion of the sinful spirit with other forms, and permitting its transmigration to other bodies, in which, by the penance it undergoes, and the trials to which it is exposed, its iniquity may be washed away, and satisfactory preparation be made for its absorption in the ocean of infinite purity. Considering thus the relation in which all animated nature stands to us, being a mechanism for purification, this doctrine of the transmigration of the soul leads necessarily to other doctrines of a moral kind, more particularly to a profound respect for life under every form, human, animal, or insect. [Sidenote: The religious use of animal life.] The forms of animal life, therefore, furnish a grand penitential mechanism for man. Such, on these principles, is their teleological explanation. In European philosophy there is no equivalent or counterpart of this view. With us animal life is purposeless. Hereafter we shall find that in Egypt, though the doctrine of transmigration must of course have tended to similar suggestions, it became disturbed in its practical application by the base fetich notions of the indigenous African population. Hence the doctrine was cherished by the learned for philosophical reasons, and by the multitude for the harmony of its results with their idolatries. [Sidenote: Of proper modes of devotion.]
