IV. The Descent to a New Birth

But let it not be imagined that the human being has nothing to do except to care for himself; as well as this he has very important work to do in Devachan. We can form an idea of this if we consider for a moment the evolution of the earth. How greatly certain regions have changed since a couple of thousand years ago! There were then quite different plants, different animal forms, even the climate was different. In respect of the products of nature the earth's surface is continually changing. In Greece, for example, there could never again arise what sprang forth from the soil in the days of ancient Greece. Evolution proceeds precisely through the fact that the face of the earth undergoes constant change.
