Esoteric Lesson

6. About the various members of the human being: the physical body, the etheric body, the astral body, and the I. The etheric body has worked on the physical body up to now. But in earlier times, forces were hidden in the etheric body that human beings have not been able to use. A large amount of the forces contained within remain unused. Then came a time when these forces had to be used for higher development, and eventually this force will become weaker and weaker, so that a time will come when the physical body can no longer be completely sustained by the force ... [illegible word]. The physical body will gradually dry up, and in later incarnations we will have increasingly inferior bodies at our disposal.
