That which develops in us as we grow, is, after all, connected very deeply with our destiny. Only to choose grotesque and radical examples, we may have grown in such a way as to be short and thick-set, or tall and lanky, as the case may be; or so as to receive this or that shape of nose. In short, the way we grow is not without its influence on our external form. And this is certainly connected, in however loose a way, with our destiny. But our way of growth is expressed not only in these crude externals. If our instruments and methods of investigation were only delicate enough, we should discover that every man has a different composition of the liver, of the spleen, or of the brain. “Liver” is not simply “liver”; it differs — though in its finer aspects, needless to say — in every human being. And this is connected with the same forces which cause plants to grow. As we look out over the plant-bedecked earth, we should be conscious: That which pours in from the wide ether-spaces, causing the plants to grow, works in us human beings too, bringing about the original and native predisposition of each one of us, and this has very much indeed to do with our destiny. For it belongs very deeply to his fate, whether a man receives out of the ether-world this or that constitution of liver, lung or brain.
