One of the greatest mysteries in life is the mystery of time. Everything that happens to us, happens to us in and through time. Time is the force that brings every new experience to the door of your heart. All that happens to you is controlled and determined by time. Time opens up and opens out the mystery of the soul.
Breathing is one internal function that the conscious mind can control with comparative ease. The effect of controlled breathing is almost like communication with all conscious parts of one's being saying to them, "Simmer down and listen; there is something beyond the turmoil". It is communication in action that often works when words merely go in one ear and out the other, not even changing the cognitive mind. In essence, the effect is to turn all the elements of our will toward stillness and waiting.
