The persistence of the human soul after physical death proves only that it is a candidate for immortality. The race is just begun. The path that leads onward to the eternal heights is so long, so beset with difficulties, with pains and penalties, losses and crosses, and all the paraphernalia of evolution and growth that the stoutest heart, the strongest will would fail to respond to the call to "come up higher," were one to at once become aware of what inevitably lay before him. When any individual soul has dwelt long enough in the spirit realm to begin to feel the unrest of the law of eternal progress, he senses the law of reincarnation, and his earthly home draws him by attraction. He is preferred the cup of "renunciation," and forgetfulness, and is shown the way to his next embodiment.
