It's actually a lyric from Dave Carter and Tracy Grammer's "The Mountain"—which I recently found out contains Sumerian. I had always assumed that the syllables chanted underneath the last verse were Sanskrit or Tibetan or some other Buddhist-appropriate language. Nope. I can't tell if this is real Sumerian quoted from some hymn or inscription, mind you, or sort-of Sumerian put together from a dictionary. Ainsley?
