7. The Physical Body Binds Us to the Physical World, the Etheric Body to the Cosmos
A contemplation of the relationship of the etheric body to the world as a whole brings us closer to this riddle. Everyone knows as a fact of experience that our physical bodies age; we grow older and older physically. And everyone understands what is involved in aging. But where our etheric bodies are concerned the opposite is true: we grow younger, ever younger. When we are very old, our physical bodies are old, but our etheric bodies have grown young. Some of you have already heard of this in my lectures, but I want to discuss it today in a different context. We have to develop our etheric bodies during an incarnation in such a way that when we have come to its close, our astral bodies will be so embedded in these etheric bodies that they feel themselves prepared for their appropriate entrance into the next life. It is really true that when an individual is old and gray and wrinkled, his etheric body burgeons with fresh life, for his astral body must accustom itself at this point to live in an etheric body already teeming with germinal potential. The way the astral body is to permeate and work in the physical body of a child in the following incarnation must already find some degree of expression in its connection with the etheric body grown young.
