There's a thread you follow. It goes among things that change. But it doesn't change. People wonder about what you are pursuing. You have to explain about the thread. But it is hard for others to see. While you hold it you can't get lost. Tragedies happen; people get hurt or die; and you suffer and get old. Nothing you do can stop time's unfolding. You don't ever let go of the thread.
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.
