2. How Can Spiritual Research Be Justified?

If someone who really wants to become a spiritual researcher wants to make his soul, so to speak, an apparatus for spiritual research, he must artificially create a similar state in himself to that which otherwise occurs in a state of sleep. That is to say, he must artificially be able to induce, through sharp concentration of will, what otherwise only occurs as a state of sleep through fatigue. He must be able to exclude all external sense impressions, must also be able to suppress all thinking bound to the brain, and yet he must avoid that state which otherwise occurs during sleep: the complete emptiness of consciousness. He avoids this by devoting himself to very specific ideas - we will characterize them later - that are suitable for concentrating his soul powers, contracting them so that they become stronger than they otherwise are. During sleep, when they leave the physical body, they are otherwise, as it were, thin and therefore unable to perceive anything of themselves or the world, their inner power of perception is too weak. Through meditation and concentration, however, they become stronger and denser. The person then withdraws from ordinary thinking not so much that he knows nothing of himself, as is the case in ordinary sleep, but so that he is able to consciously hold himself and, through the nature of this state, experiences: Now you hear nothing through the ears, see nothing more through the eyes, think no longer through the brain-bound thinking, but now you experience yourself in the pure spiritual and have a reality in the pure spiritual.
