1. Knowledge of Nature and Knowledge of the Mind

It is remarkable: with the expansion of material knowledge, the sense of self becomes stronger. If, so to speak, you are absorbed in material knowledge, you initially achieve the maximum of the ordinary sense of self. — When does it weaken? Well, you only need to recall the most ordinary, everyday phenomenon that shows when the sense of self weakens. I remind you of the dream, of dreaming. It is not necessary that something has an external reality meaning when you look at this something in order to recognize from it how to enter into true reality. Dreaming can ultimately be made the subject of extraordinarily interesting research, and Johannes Volkelt, a very important philosopher of modern times, published his book on dream fantasy as one of his first literary works. It is a pity that Volkelt then left the paths he had taken with it and through which he could have come very close to real spiritual scientific knowledge, under the power of the latest philosophy. If one really studies the life of dreams, one notices in the course of the dreams many things, but one of the most essential characteristics of interesting dreams is their symbolism. Let us say, for example, that there is some kind of fire alarm outside on the street, but we are still asleep and do not recognize the fire alarm as such. The dream sometimes symbolizes some event to us, which we then recognize when we awaken, as it is symbolic of what appears as an external fire alarm. This is an example of the symbolization of external events. But it is the same with internal states. We dream of a boiling oven and when we awaken we recognize that the boiling oven is the dream symbol that is placed before us for the pounding heart with which we awaken. The dream symbolizes the inner and the outer for us in the strangest way. But we will not be able to deny it: the dream realm represents that in which our ego, so to speak, loses itself again. It goes so far that we experience in our dreams what can only come from our own ego as if it were coming from an alien ego. The dream dissolves our ego, so to speak, as the chaotic manifestation of our soul life, our soul life that is not initially connected to the outside world. It brings us out of the composure into which we grow more and more, especially when we devote ourselves to material knowledge.
