Seventh Lecture
In his study of earth-evolution, the Egyptian initiate saw that the god Osiris had separated himself from the sun and had gone to the moon, whence he reflected the light of the sun. What this god did was also sacred to the Greeks. They too knew that it was this god, Osiris, who formed the twenty-eight moon-aspects, and thereby laid the groundwork for the twenty-eight nerves in man. Through Osiris, the nervous system is built onto the spinal column, thereby forming the whole upper body of man. For what appears as muscle can maintain its form only because the nerves are its shapers. All we have as muscles, cartilage, and other organs such as heart and lungs, maintains its form only through the nerves. Thus through the earlier sun-activity appeared what took form as brain and spinal column, and on this spinal column the twenty-eight aspects of Isis and Osiris work from outside. Isis and Osiris are the shapers of all this, and in the tentacles that the brain sends down into the spinal column, Osiris works upon the spine. The Greeks experienced this also, and as they became acquainted with the Egyptian mysteries they recognized that Osiris was the same as the god whom they called Apollo. They said that the Egyptian Osiris was Apollo, and that, like Osiris, Apollo worked upon the nerves so as to achieve a soul-life within man.
