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.
Our greatest resource in reversing the effects of this violent culture, and changing it into a culture of peace, comes from spirituality, and all that rich term implies... Profoundly transformative, it can dissolve the destructive patterns of the culture of violence which have held us captive for so long a time. Spirituality, as the inner yearning of the heart for the Divine, for the Real, awakens in us openness, gentleness, patience, deep reverence for all life forms, including the earth, intense compassion for all sentient beings, and an all-inclusive love, agape, that embraces the totality.
