A brief excerpt taken from Richard Rohr's daily mediation: The YHWH Prayer
"A rabbi taught this prayer to me many years ago. The Jews did not speak God’s name, but breathed it with an open mouth and throat: inhale--Yah; exhale--weh. By our very breathing we are speaking the name of God and participating in God’s breath. This is our first and our last word as we enter and leave the world."
