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.
On Thee the Angels look and are at peace; that is why they have perfect bliss. They never can lose their blessedness, for they never can lose Thee. They have no anxiety, no misgivings -- because they love the Creator.
~ from MEDITATIONS AND DEVOTIONS by John Henry Newman
