"Tell me who it is who brings about the re-birth (the revolutio)?" is asked of the wise Hermes. "God's Son, the only man, through the will of God," is the answer of the "heathen." "God's son" is the immortal spirit assigned to every human being. It is this divine entity which is the "only man," for the casket which contains our soul, and the soul itself, are but half-entities, and without its overshadowing both body and astral soul, the two are but an animal duad. It requires a trinity to form the complete "man," and allow him to remain immortal at every "re-birth," or revolutio, throughout the subsequent and ascending spheres, every one of which brings him nearer to the refulgent realm of eternal and absolute light.
