On Sleep

Generally, when you have what you call dreamless sleep, it is one of two things; either you do not remember what you dreamt or you fell into absolute unconsciousness which is almost death – a taste of death. But there is the possibility of a sleep in which you enter into an absolute silence, immobility and peace in all parts of your being and your consciousness merges into Sachchidananda. You can hardly call it sleep, for it is extremely conscious. In that condition you may remain for a few minutes, but these few minutes give you more rest and refreshment than hours of ordinary sleep. You cannot have it by chance; it requires a long training.
