Breath and attention to breath are keys to self-emptying. Attending to the breath will carry you beyond the distractions of the mind and return you to the Greater Unity of God from which you arise and in which you dwell. Just as God breathed life into Creation, so God breathes into each one of us at this and every moment. Follow the breath back to God.
Prayer begins in us the restoration of the divine image, in all its hiddenness and wonder. It brings us closer to the "region of likeness" and every prayer is an act of letting the old self go. It involves "dying". The grain of wheat falls into the ground and dies. Dead, it is destined to bear much fruit.
