10. The Supernatural Essence of Man and the Development of Humanity
Then one comes to an inner discovery, to an inner experience, which I would now like to describe as the second shattering event on the way into the supersensible worlds: one experiences inwardly that one's ordinary thinking cannot be distinguished from one's outer physical activity; but that the thinking that one develops through one's own power, that proceeds in such a way that one experiences it: It has nothing to do with any external physical activity; it has nothing to do with any nervous or other activity. When you think as I have just described, you know that you are moving in a purely spiritual element with your thinking, and you have your physical self beside you; you have really stepped out of your body. And now you realize that this human being, when it carries out its thinking in this way, when it carries out its inner soul activity, as it is often described in the everyday illusions of human beings. People also believe in many cases, based on today's popular science, that they are indulging in materialistic ideas: we have developed the nervous system into the wonderful brain; in this brain one can see how research in human development is progressing; with each stage of thinking, the brain develops further. And then people say: So thinking, imagining, arises through the activity of the brain, through the activity of the nervous system. And basically, people who know nothing of the independent bodiless thinking that I have just described to you cannot help it, if they are somehow religious, but think of the illusory body.
