Lecture I

We do not realise today that besides, shall I say, the coarse inhaled with the air, all kinds of substances are present, but in a state of exceedingly delicate, fine distribution. Those substances, too, which in present earth-existence are in the solid, mineral condition, are contained in the air in fine, delicate distribution, and the human being breathes them in. Now the peculiarity of these substances in their state of fine distribution through the air, is that they have the tendency to assume forms and shapes. Earthly substances too, of course, assume the forms we know as the mineral crystals. I am not here referring to the crystals but to substances finely distributed in the air, or one might also say, in the air-ether, inasmuch as this plays through the air. These substances, too, build forms—forms that do not resemble those of the minerals but of the organs in man. This is a peculiarity of the ether, which pervades the air. When we can observe this ether with Imaginative Knowledge, we see within it floating forms, delicate ether-forms with the shape of lung, or liver, or stomach—at any rate, shapes of the inner organs of man. With trained etheric sight all these forms can be observed in the cosmic ether. In comparison with our physical organs, however, these cosmic forms are usually of gigantic dimensions. We see gigantic ether-forms, with the shapes of liver, lung, and so on, interpenetrating the cosmic space around us. These forms, floating as it were in space, are breathed in by man—and it is good that this happens. For as man inbreathes these forms which enter into him with the air, they work beneficially and with healing effect upon his organs. Organs, after all, deteriorate as life progresses and, to speak colloquially, they are patched up again by what is inbreathed in this way. We well know how difficult it is for therapy to restore the physical organs, but this other kind of therapy works effectively and continuously upon the human being.
