Death is the laying aside of the physical body; but it makes no more difference to the ego than does the laying aside of an overcoat to the physical man. Having put off his physical body, the ego continues to live in his astral body until the force has become exhausted which has been generated by such emotions and passions as he has allowed himself to feel during earth-life. When that has happened, the second death takes place; the astral body also falls away from him, and he finds himself living in the mental body and in the lower mental world. In that condition he remains until the thought-forces generated during his physical and astral lives have worn themselves out; then he drops the third vehicle in its turn and remains once more an ego in his own world, inhabiting his causal body. There is, then, no such thing as death as it is ordinarily understood. There is only a succession of stages in a continuous life--stages lived in the three worlds one after another. The apportionment of time between these three worlds varies much as man advances. The primitive man lives almost exclusively in the physical world, spending only a few years in the astral at the end of each of his physical lives. As he develops, the astral life becomes longer, and as intellect: unfolds in him, and he becomes able to think, he begins to spend a little time in the mental world as well. The ordinary man of civilized races remains longer in the mental world than in the physical and astral; indeed, the more a man evolves the longer becomes his mental, life and the shorter his life in the astral world. The astral life is the result of all feelings which have in them the element of self. If they have been directly selfish, they bring him into conditions of great unpleasantness in the astral world; if, though tinged with thoughts of self, they have been good and kindly, they bring him a comparatively pleasant though still limited astral life. Such of his thoughts and feelings as have been entirely unselfish produce their results in his life in the mental world; therefore that life in the mental, world cannot be other than blissful. The astral life, which the man has made for himself either miserable or comparatively joyous, corresponds to what Christians call purgatory; the lower mental life, which is always entirely happy, is what is called heaven.
