2. Meditation

If you think this over you will say to yourself: There, outside, are the substances of the different kingdoms of Nature. They are, today, just what they have become; but they have certainly not always been as they are. Even physical science admits that past conditions of the earth were very different from those of today. What we see around us in the kingdoms of Nature has only gradually become what it is. And when we look at man's physical body we see it destroys—or transforms—what it takes in. (We shall see that it really destroys, but for the moment we will say ‘transforms’.) At any rate, what is taken in must be reduced to a certain condition from which it can be led back again to present physical Nature. In other words: If you think of a beginning somewhere in the human organism, where the sub-stances begin to develop in the direction of excretions, and then think of the earth, you are led to trace it back to a similar condition in which it once was. You have to say: At some past time the whole earth must have been in the condition in which some-thing within man is today; and in the short space of time during which something incorporated into the human organism is transformed into excretory products, the inner processes of the organism recapitulate what the earth itself has accomplished in the course of long ages.
