The 'Mountain of Blessings', a prayer and guide to perfection written by Lama Tsong Khapa as a preparation for the tantric teachings. He wrote the work after experiencing a prophetic vision over the length of an entire month at Reting monastery. A full commentary is given by Pabongka Rinpoche to this important text, which has become a standard teaching given by lamas before tantric teachings ever since. It deals mainly with the preliminaries.
