Swami VivekanandaNot 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.
Swami Vivekananda
