Tenth Lecture

The ego organization is the spiritual inner self. We have silicic acid in our hair, in our bones, in our sensory organs; we have silicic acid distributed throughout the entire periphery of the body. Wherever the human being comes into contact with the forces of the outside world, there is silicic acid. This silicic acid is the external correlate, the outward activity of the ego organization. Astral body: the inner spiritual; carbonic acid process: the outer physical. Silicic acid process: the outer physical; ego organization: the inner.
