Volume Five focuses on the lineages of great teachers who have transmitted the Tibetan Buddhist teachings and on the practice of devotion to the spiritual teacher. It includes inspirational commentaries by Chögyam Trungpa on the lives of famous masters such as Padmasambhava, Naropa, Milarepa, Marpa, and Tilopa, as well as an excerpt from The Sadhana of Mahamudra, a tantric text that Chögyam Trungpa received as terma in 1968. Among the selected writings are "Explanation of the Vajra Guru Mantra," an article never before published, which deals with the mantra that invokes Guru Rinpoche; seminar talks available in book form for the first time; and previously unpublished articles on Milarepa.
