Unless we are grounded in Mystery -- unless we experience both ourselves and others as co-participants in Mystery -- we find it almost impossible to live in compassionate love of one another for any length of time. Unless we have "new eyes" that can see others contemplatively, it is easy to miss the many-spendored thing that is our life together.
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.
