Great Accomplishment offers detailed explanations of the Vajrayana practices in the drubchen ceremony and the underlying theories from which they derive. It gives hands-on advice on the meaning, application, and profound results of working together with other practitioners in this way to accomplish the goal of taming our minds and benefiting others. From the most esoteric to the subtlest of practical details, three masters -- Tulku Urgyen Rinpoche, Orgyen Topgyal Rinpoche, and Lama Putsi -- give a complete guide to this hidden treasure.
