When a person is angry with another person, that person is removed from their heart. That's why the physical reaction is to shout. The greater the distance, the louder the shouting. But when individuals are in love, they speak softly, and when they are further in love, no words are needed.
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.
