2. The Human Soul, Destiny and Death from the Point of View of Spiritual Science
Not that the spiritual researcher does not need sleep; he does need it. But he can artificially induce states in which he is able to experience as otherwise only happens to a person from falling asleep to waking up. For the spiritual researcher knows, by experiencing the following: You are outside your body, you develop an activity that is not dependent on the brain and nervous system, and he comes to understand through actual experience what is experienced from falling asleep to waking up. He comes to recognize that in fact the human being's actual spiritual-soul entity is outside of the body, that when a person falls asleep, he leaves his body with his spiritual-soul entity and when he wakes up, the spiritual-soul entity once again enters the body.
