In the chapter, Winning the Debate Arisen Through Jealousy, a local monastery sends three teachers to visit the Jetsun in order to humiliate him and make him leave the area.
When asked if Milarepa knows the generation stage practices and meditates on them, he replies with this song. Rinpoche always emphasizes that all generation stage practices are included within this song and uses it often to guide in meditation.
You can find restricted teachings where Rinpoche devotes a talk on this song in the recordings from Karmê Chöling, 1993, Boulder 1999, and in the recording found here, from Kamalashila, Schloss Wachendorf, 1982.
