God is dynamically present in every breath and heartbeat. In each breath we draw, the Spirit gives life. Learning to reclaim the deep, nourishing breaths of infancy is part of basic training not only in health and movement classes, but in prayer and meditation practices around the world. The deep, full breathing required to sing may well have similar importance in praying well: nothing reminds us more literally than inbreathing and outbreathing that we continually receive life and must continually release what we have received in order to receive again.
Compassion literally means to feel with, to suffer with. Everyone is capable of compassion, and yet everyone tends to avoid it because it's uncomfortable. And the avoidance produces psychic numbing -- resistance to experiencing our pain for the world and other beings.
