1. First Steps towards Imaginative Knowledge

You will no doubt be aware that when a person's sense-impressions have been gradually shut off; when all is dark around him and he can see nothing; when all noise is shut out so that he hears nothing and even the day's impressions are suppressed, he falls asleep. This empty consciousness, that comes to anyone on the verge of sleep, now has to be brought about at will. But while all conscious impressions, even those self-induced, have to be blotted out, it is most important for the student to remain awake. He must have the strength, the inner activity, to keep awake while no longer receiving impressions from without, or any experiences whatever. An empty consciousness is thus produced, but an empty consciousness of which one is fully aware.
