On the other hand, when the Ego, during life, has always refused the appeals of the lower nature, it easily withdraws, after death, from the net of passion, the substance it has infused therein, and passes with this substance into that part of the mental plane which is called "heaven." Such is the struggle that Egypt committed to her annals when she inscribed upon papyrus or engraved upon stone the journeyings of the soul into the world of shades. The soul--the mental personality--which demands "osirification," and invokes the Ego, its god and projector, beseeching him to draw it to himself that it may live with him, is the lower "I." This "I" has not exhausted the "desire to live" on earth; its desire is impressed on the germs it has left in the causal body, and brings the Ego back to incarnation; this is the reason it prays and desires the resurrection[117] of its "living soul," the Ego. Denon, in his _Journeyings in Egypt_, has made known to us the Sha-En (the book of metamorphoses), written in hieratic signs and republished in Berlin, by Brugsch, in the year 1851. Explicit mention is here made of reincarnations, and it is stated that they are very numerous. The third part of the _Book of the Dead_ sets forth a detailed account of the resurrection of an Osiris; the identification of the departed one with Osiris, God of Light, and his sharing in the life, deeds, and power of the God; in a word, it is the final reintegration of the human soul with God. The loftiest and most suggestive of Egyptian palingenetic symbols is unquestionably that of the egg. The deceased is "resplendent in the egg in the land of mysteries." In Kircher's _Oedipus Egyptiacus_[118] we have an egg--the Ego freed from its vehicles--floating over the mummy; this is the symbol of hope and the promise of a new birth to the soul, after gestation in the egg of immortality.[119] The "winged globe," so widely known in Egypt, is egg-shaped, and has the same meaning; its wings indicate its divine nature and prevent it from being confused with the physical germ. "Easter eggs" which are offered in spring, at the rebirth of Nature, commemorate this ancient symbol of eternal Life in its successive phases of disincarnation and rebirth. CHALDAEA. It is said that the Magi taught the immortality of the soul and its reincarnations, but that they considerably limited the number of these latter, in the belief that purification was effected after a restricted number of existences on the soul returning to its heavenly abode.
