Book excerpt: The Song That I Am: On the Mystery of Music is a short but full-to-the-brim essay on the decisive role that great music (whether Bach, Tavener, or Gregorian chant) ought to play in the spiritual life. With admirable restraint Élisabeth-Paule Labat shares her interior experience of music and thus continually opens up fresh vistas through worlds of sound and spirit. With her uncanny gift of language, Labat precisely describes soundings and yearnings of the soul that many of us glimpse fleetingly. Because "only the lover sings" (St. Augustine), her final illumination is that the experience of profound music ought to transform us into the beauty that we hear.
