Swami Rama

The finest hours are the hours of night, but very few know how to utilize their worth and silence. Three categories of people remain awake at night: the yogi, the bhogi, and the rogi. The yogi enjoys bliss in meditation, the bhogi enjoys sensual pleasures, and the rogi keeps awake because of his pain. All three remain awake,  but benefited is he who is in meditation.
