At the extremity of prayer words vanish, or rather the "silence-become-word" surpasses all that can be uttered. Prayer becomes the silence of Love, and this silence reveals the "I" in its deepest aspects; and, should words suddenly arise in prayer, we must regard them as fruits of love that send us back to silence.
Breathing is the connection between the mind and the body. When the mind concentrates on the breath, it focuses attention on the present moment. Breathing is the first step on the path to discover your spiritual nature. As you get the body to breathe correctly, the mind settles down, and that creates fertile ground to develop whatever spiritual nature exists within you.
