9. The Sleeping-and-Waking Rhythm in the Context of Cosmic Evolution

We use up some of the light we have taken in; we consume light. There is something else we consume, but let us for the moment just consider the fact that we use up heat and light. These things we take in make happen what I spoke of a week ago, that something evolves which is very delicate and alive. When we are thinking in the ordinary everday way, something lives within us that leaves its imprint on the organism, triggering a process that also has to do with heat; it leaves its imprint and the process which takes place causes us to have memory. This, however, must not happen when we meditate. When we live in a pure thought or feeling content, separate from everything else, the heat, light, etc., we consume does not leave its imprint on the body, it leaves its imprint in the general ether. It triggers a process outside us. Dear friends, if you are seriously, genuinely meditating, you are impressing your thought form into the general ether; it will be there within it. And if you then look back on a meditation this will not be the usual way of remembering; You are looking back to something which has left its imprint in the cosmic ether.
