The Enhancement of Human Cognitive Ability to Imagination, Inspiration and Intuition
Man thinks all too little about what comes into consideration there because, if he is not exactly blind, the lion's share of what he is conscious of in his experience comes from the eyes, and the eyes are precisely those organs that are closed in the human sleeping state, whereby the external impressions are kept out. But think of the other senses. Can you believe that your ear, if you do not block it, gives you different experiences during sleep than during the day in relation to the physical body? If you keep the physical body properly in mind and do not block your ear at night, you cannot possibly think that something different happens through the ear in your physical organism when you are asleep than when you are awake. There is no reason for it. The fact that you don't know that is quite another matter.
