Explains the difference between the spirit and the soul, and the need to create or "synthesize" a new type of soul, which is not animal but truly human. The Sexual Hydrogen SI-12 is explained and how the Solar Astral, Mental, and Causal bodies are crystalized through sexual alchemy, and much more. A quote from the lecture: Every act of sexual alchemy or sexual magic is a baking of spiritual bread. The bread is fed to the inner Being. This is what they called in Egypt the sepulchral cakes of the city of Pe, which is in lower Egypt. Egypt is the body, lower Egypt is the sexual organs. The cakes of the city of Pe are brought up to the city of Heliopolis, which is upper Egypt. God, the Inner Being, feeds on those breads. We have to continue to bake and re-bake in order to make a better bread that is more nourishing. In the beginning the bread is of a certain quality which nourishes the inner Being, but as you remove the impurities and learn how to become more scientific within your own psychological laboratory, and you bake a better bread to nourish your Being at a superior level.
