Next I saw the most lucid air, in which I heard in a marvelous way many kinds of musicians praising the joys of the heavenly citizens. ... And their sound was like the voice of a multitude, making music in harmony.
~ Hildegard of Bingen
Song is not a luxury, but a necessary way of being in the world. If you are cut off, in pain, estranged, numb — sing, give voice to anything. It needn't sound pretty. Simply, bravely, open despite the difficulty, and let what is in out, and what is out in. Sing and your life will continue.
