I. Spiritual Science and the Future of Humanity
There that technique to which spiritual science refers shows that we have to talk of unconsciousness in this case of falling asleep only because we cannot develop so strong forces if all outer impressions stop, that the soul feels its own being and that it cannot establish a relationship to its environment in which it is then and which is spiritual. If now the human being opens himself to particular contents of thought and feeling, he can also feel as a being if all outer impressions are quiet. Then he is in the same situation as someone is who sleeps, and, nevertheless, his situation is radically different. He can exclude all outer impressions consciously and by his will and everything that speaks, otherwise, in the wake state to him by the senses and the reason. Then he is not unconscious but lets the full contents of the soul life light up.
