The more we look at sleeping and waking from a psychological point of view, the more we shall come to the conclusion that they are not as we understand them, but that every moment of the day and the night we are awake and asleep at the same time. To give another instance: when a person is asleep and experiencing a dream, he is awake to something and yet asleep to the outer things. To one world he is asleep, to the other awake. So one is always asleep and always awake.
