People can live only by dwelling in the living breath of God. Only in this way can they be at peace and realize their aspirations. From sunrise to sunset, they dwell in the living breath of God; every sight and thought is part of that breath. God provides a place for them filled with clarity and bliss and stillness. In the silence, we are moved by this wind, which blows everywhere in the world.
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.
