In October 2006 Rinpoche held the first Riwo Sangcho retreat at Pema Osel Do Ngak Choling. He gave two talks during the retreat -- a commentary on the text, and a long talk on the subject of Lenchak. These talks and a sample practice session are included on this MP3 CD, to aid in learning the melody. The long talk on Lenchak is included in the "Lenchak" compilation, sold above.
NOTE: These recordings are open to the public, though only those who have received Riwo Sangcho initiation from Rinpoche should do the practice.
