VII. Inner Processes in the Human Organism. Sense-Perception, Breathing, Sleeping, Waking, Memory

In Spiritual Science it has always been the endeavor to discover methods through which man may acquire true self-knowledge, and you are aware from the many different lectures I have given, that by this self-knowledge I do not mean the ordinary kind of brooding contemplation of the everyday self; for all that a man experiences thereby is simply a reflex picture of the external world. He learns nothing that is new; he merely gets to know, as it were in a mirror, what he has experienced in the outer physical world. True self-knowledge must, as you know, proceed through methods which silence not only the earthly outer world, but also the everyday soul-content which, as it exists in actual consciousness, is simply a mirror-picture of the outer world. And through the methods described in the book Knowledge of the Higher Worlds and Its Attainment, you know that spiritual research advances first to what is called Imaginative Cognition. Whoever advances to this Imaginative Cognition has before him, to begin with, everything from the supersensible world that can clothe itself in the images and pictures of this form of higher knowledge. And when he has acquired the inner faculty of Imaginative vision of the world, he is in a position to follow what takes place in the human sense-organs.
