There is a drowsy state, between sleeping and waking, when you dream more in five minutes with your eyes half open, and yourself half conscious of everything that is passing around you, than you would in five nights with your eyes fast closed, and your senses wrapt in perfect unconsciousness. At such time, a mortal knows just enough of what his mind is doing, to form some glimmering conception of its mighty powers, its bounding from earth and spurning time and space, when freed from the restraint of its corporeal associate.
It is most important to allow the brain the full measure of sleep which is required to restore it; for sleep is to a man's whole nature what winding up is to a clock.
Not even the deepest sleep will give you such a rest as meditation can. The mind goes on jumping even in deepest sleep. Just those few moments in meditation your brain has almost stopped. ... You forget the body. ... You feel such pleasure in it. You become so light. This perfect rest we will get in meditation.
Sleep is the interest we have to pay on the capital which is called in at death; and the higher the rate of interest and the more regularly it is paid, the further the date of redemption is postponed.
