Lecture III
As soon as one becomes fully aware what actually takes place in the soul when one thinks, when one visualizes, then one will gradually be able to arrive at an inner grasp of the soul-physical process that is taking place, even without occult training. And this soul-physical process of thinking, of imagining, is one that, even in its soul characteristics, shows that it is the opposite of another process. Just try to find, in the realm of ordinary consciousness, what the opposite process of thinking is. It is the process in which our thoughts fade away, where we become incapable of pursuing thoughts in a bright, clear way, where, in other words, what we call consciousness in ordinary life ends, at least where our control over what we call consciousness in ordinary life ends. Now you can see how this counter-image of thinking has a physical correlate: Wherever the actual growth process, the process of becoming in us, the process of nourishing and growing, is particularly strong, the thought element, the element of imagination, recedes. You only need to look intelligently at the lively organic growth activity in the first years of childhood. This growth activity is particularly vivid then. But thinking is only present in the germ, at least the power of the human being over thinking. Or follow disease processes through which, as in feverish phenomena, the organic activity becomes particularly vehement, where it becomes intensified, there the conscious control over the life of imagination fades away.
