GREAT EASTERN SUN
Normally, when you see a brilliant light, that light comes from a finite source of energy. The brightness of a candle depends on how much wax surrounds it, and the thickness of the wick. The brightness of a light bulb depends on the electric current running through it. But the Great Eastern Sun is eternally blazing; it has no need of fuel. There actually is greater luminosity that occurs without fuel, without even a pilot light. Seeing the sacred world is witnessing that greater vision, which is there all the time.
