2. Blood and Nerves

Our blood has entered our organism as a result of processes belonging specifically to the earth. Blood is essentially of an earthly nature. You know that the development of the human being had been prepared long before the earth existed during the Saturn, Sun, and Moon phases of evolution.[^1] What was prepared there did not yet have any blood. Human blood, as it flows through our veins today, was added during our earth evolution. In contrast to that, the structure and development of the nervous system contains what had long ago been prepared in the Saturn, Sun, and Moon phases of evolution through processes that preceded our earth organization.
