"The doctrine of Metempsychosis may almost claim to be a natural or innate belief in the human mind, if we may judge from its wide diffusion among the nations of the earth, and its prevalence throughout the historical ages."--_Prof. Francis Bowen_.

"When Christianity first swept over Europe, the inner thought of its leaders was deeply tinctured with this truth. The Church tried ineffectually to eradicate it, but in various sects it kept sprouting forth beyond the time of Erigina and Bonaventura, its mediaeval advocates. Every great intuitional soul, as Paracelsus, Boehme, and Swedenborg, has adhered to it. The Italian luminaries, Giordano Bruno and Campanella. embraced it. The best of German philosophy is enriched by it. In Schopenhauer, Lessing, Hegel, Leibnitz, Herder, and Fichte, the younger, it is earnestly advocated. The anthropological systems of Kant and Schelling furnish points of contact with it. The younger Helmont, in _De Revolutione Animarum_, adduces in two hundred problems all the arguments which may be urged in favor of the return of souls into human bodies according to Jewish ideas. Of English thinkers, the Cambridge Platonists defended it with much learning and acuteness, most conspicuously Henry More; and in Cudsworth and Hume it ranks as the most rational theory of immortality. Glanvil's _Lux Orientalis_ devotes a curious treatise to it. It captivated the minds of Fourier and Leroux. Andre Pezzani's book on _The Plurality of the Soul's Lives_ works out the system on the Roman Catholic idea of expiation."--E.D. WALKER, in "_Re-Incarnation, a Study of Forgotten Truth_."

And in the latter part of the Nineteenth Century, and this the early part of the Twentieth Century, the general public has been made familiar with the idea of Metempsychosis, under the name of Re-incarnation, by means of the great volume of literature issued by The Theosophical Society and its allied following. No longer is the thought a novelty to the Western thinker, and many have found within themselves a corroborative sense of its truth. In fact, to many the mere mention of the idea has been sufficient to awaken faint shadowy memories of past lives, and, to such, many heretofore unaccountable traits of character, tastes, inclinations, sympathies, dislikes, etc., have been explained.

The Western world has been made familiar with the idea of the re-birth of souls into new bodies, under the term of "Re-incarnation," which means "a re-entry into flesh," the word "incarnate" being derived from the words "_in_," and "_carnis_," meaning flesh--the English word meaning "to clothe with flesh," etc. The word Metempsychosis, which we use in this lesson, is concerned rather with the "passage of the soul" from one tenement to another, the "fleshly" idea being merely incidental.

The doctrine of Metempsychosis, or Re-incarnation, together with its accompanying doctrine, Karma, or Spiritual Cause and Effect, is one of the great foundation stones of the Yogi Philosophy, as indeed it is of the entire system of systems of Oriental Philosophy and Thought. Unless one understands Metempsychosis he will never be able to understand the Eastern Teachings, for he will be without the Key. You who have read the _Bhagavad Gita_, that wonderful Hindu Epic, will remember how the thread of Re-Birth runs through it all. You remember the words of _Krishna_ to _Arjuna_: "As the soul, wearing this material body, experienceth the stages of infancy, youth, manhood, and old age, even so shall it, in due time, pass on to another body, and in other incarnations shall it again live, and move and play its part." "These bodies, which act as enveloping coverings for the souls occupying them, are but finite things--things of the moment--and not the Real Man at all. They perish as all finite things perish--let them perish." "As a man throweth away his old garments, replacing them with new and brighter ones, even so the Dweller of the body, having quitted its old mortal frame, entereth into others which are new and freshly prepared for it. Weapons pierce not the Real Man, nor doth the fire burn him; the water affecteth him not, nor the wind drieth him nor bloweth him away. For he is impregnable and impervious to these things of the world of change--he is eternal, permanent, unchangeable, and unalterable--Real."
