passes in this rest are the real sleep which restores – if one does not get it, there is only a half rest. It is when you come near to either of these domains of rest, that you begin to see these higher kind of dreams.Sri Aurobindo

In sleep one very commonly passes from consciousness to deeper consciousness in a long succession until one reaches the psychic and rests there or else from higher to higher consciousness until one reaches rest in some silence and peace. The few minutes one passes in this rest are the real sleep which restores – if one does not get it, there is only a half rest. It is when you come near to either of these domains of rest, that you begin to see these higher kind of dreams.
