If I were to explain from what all this manifestation has come, how it has been produced and into what it will turn, it would take a very long time. It is a long subject, but in a few words I can say: How could there be room on this earth for all the people that ever have been, if this matter remained as we see it? Even for the people living on earth where they are many, often famines come, diseases, plagues and wars. If all that matter did not return by various processes to the unseen from which it has come, there would be no room left on earth, nor in the water, nor in space. Matter is all destroyed, annihilated, and nothing can save it when the call of annihilation comes.
