What a beautiful song this is, too. I found it on the CD "Bardo Prayers" sung by Bhakha Tulku Rinpoche and Sonam Dadul, and it is so lovely.

I became so taken with this song - it's no wonder they say the young monks love to go around singing it while doing their morning chores. Here's a transcription of the version sung by the gentlemen above, if you want to sing along: http://db.tt/gsfLy7WH
