During the fast sleep ordinarily a person is conscious of nothing. When he wakes up, he feels refreshed and renewed. What are we doing while we are fast asleep? The soul then is released from the hold of the body and the mind. It is free, it goes to its own element, to the highest spheres, and it enjoys there. It is happy. All the happiness, all the wisdom of those spheres it experiences. It enjoys all the bliss, happiness and peace.
