6. Initiation-Knowledge, Waking Consciousness and Dream Consciousness
To sum up: man possesses a physical body that is perceptible to the senses; an etheric body perceptible to Imagination by virtue of the forces that can be developed through the practice of concentration and meditation in the manner already indicated. But if we try to perceive the astral body with the aid of these forces, we meet with a void, a spatial vacuum. This void is filled with content only when we attain the emptied consciousness which I have described, when we can confront the world in full waking consciousness in such a way that, though sensory impressions are obliterated and thinking and memories are silenced, we remain none the less aware of its existence. We then know that in this void we have our first spiritual vehicle, the astral body of man.
