The "Zintri" is a significant collection of notes compiled from memory by Khenpo Ngawang Palzang, an outstanding Tibetan master. These notes are the result of oral teachings that Palzang received from his master Nyoshul Lungtog Tenpai Nyima. They represent the only commentary on the works of Patrul Rinpoche and are an indispensable addition to "The Words of My Perfect Teacher." The "Zintri" conveys valuable information about the theoretical background and foundations of Buddhist practice in a clear and profound manner. The advice contained within is of great importance for both meditation sessions and daily life. Khenpo Ngawang Palzang, who completed all stages of the path to Great Perfection by the age of twenty-one, is regarded as one of the most remarkable figures of his time, known for his scholarship and spiritual realization.
