The ngondro, or preliminary, practices are the foundation of Vajrayana Buddhism. The Dudjom Tersar ngondro, a treasure revealed by Dudjom Lingpa, a previous incarnation of Dudjom Rinpoche, is a concise, yet very powerful set of practices for turning the mind to dharma, purifying obscurations, accumulating merit, and opening the door to the mind's true nature through guru yoga.
H.E. Chagdud Tulku Rinpoche (Tib. ལྕགས་མདུད་སྤྲུལ་སྐུ་, Wyl. lcags mdud sprul sku), born Padma Gargyi Wangchuk, is held to be the 14th Chagdud incarnation in a line extending from Sherab Gyaltsen, who folded an iron sword into a knot with his bare hands, thus earning the name "Chagdud" or "iron knot." Born to a lama of the Gelug school and a mother from a Sakya family, the 14th Chagdud began his training in the Kagyu school before achieving renown as a master of Dzogchen and teacher of the Nyingma school lineages of Dudjom Rinpoche and Dilgo Khyentse Rinpoche. One of the first Nyingmapa lamas to settle in the United States, he relocated to Brazil in 1995 and built the first traditional Tibetan temple in South America with his wife Jane Tromge (Chagdud Khadro).
Very informative, especially for someone who does not know much about Buddhism! I received Ngondro teachings and empowerments before reading this book and although I understood what was being taught, this book helped answer some of my questions. Although it did raise some others that I hope to have answered by one of my teachers or through some other dharma books. I highly recommend this book to anyone interested in Buddhism.
Wish someone had recommended this commentary of important instructions to me years ago however perhaps I was not ready to receive the instructions at that time. Fantastic, a jewel for any Buddhist practitioner, particularly the Vajrayana practitioner.
