Man's Threefold Nature and Relationship to Remedies

For the student who is beginning to estimate facts correctly, this is very important, for it indicates the inability of the kinsman of intestinal fauna or flora, the bacillus, to survive in the sunlight. Sunlight does not suit it. Where can the bacillus survive? In the interior of the human body. And why just there? It is not that the bacillus itself is the noxious agent, it is the forces active within the body that we must consider. And here is another fact that is ignored. We are continually surrounded by light; light—as you will of course remember perfectly from your study of science—has supreme importance for the evolution of the extra-human beings, and especially for the development of all extra-human flora. But at the border line between ourselves and the world outside, something very significant happens to light, that is, to something purely etheric; it becomes transmuted. And it needs must be transmuted. For, consider how the process of plant formation is held up in man, how this process is so to speak broken off and counteracted by the process that manufactures carbon dioxide. In the same way, the process contained in the life of light is interrupted in man. And so, if we seek for light within man, it must be something transformed, it must be a metamorphosis of light.
