Some of us have bodies that can’t keep pace with the activity of our minds or the desires of our hearts. Some of us have thoughts bursting like fireworks in our heads but which cannot find their way out of our mouths in the form of comprehensible speech. Some of our bodies pose staggering challenges for ourselves or for our loved ones. And still, our very existence is a song of praise to God, a Psalm to this Universe.
