Very Venerable Ninth Khenchen Thrangu Tulku, Karma Lodrö Lungrik Maway Senge (Tibetan: ཁྲ་འགུ་, Wylie: khra 'gu) is a prominent tulku (reincarnate lama) in the Kagyu school of Tibetan Buddhism.
At the age of four he was formally recognized by His Holiness the Sixteenth Karmapa and Eleventh Tai Situpa as the ninth incarnation of the great Thrangu tulku, the abbot of Thrangu Monastery, whose root incarnation was Shüpu Palgyi Sengé, one of the twenty-five disciples of Guru Rinpoche. Forced to flee to India in 1959, he went to Rumtek Monastery in Sikkim, where the Karmapa had his seat in exile. Thrangu Rinpoche then served as the main teacher of the four principal Karma Kagyü tulkus of that time—the four regents of the Karmapa (Shamar Rinpoche, Tai Situ Rinpoche, Jamgon Kongtrul Rinpoche, and Gyaltsab Rinpoche). In 1976 he began to teach in the West and became the abbot of Gampo Abbey—a Buddhist monastery in Nova Scotia, Canada—as well as to take charge of the three-year retreat centre at Samyé Ling in Scotland.
He is also the author of the widely studied The Practice of Tranquility and Insight, a commentary on the eighth chapter of Jamgön Kongtrul'sTreasury of Knowledge, on shamatha and vipashyana.
This is by far the most easy to digest book on the preliminary practices. I am extremely grateful for the teaching of Khenchen Thrangu Rinpoche. The preliminaries, paired with the Tonglen practice (briefly mentioned in this book) has single-handedly change my practice for the better.
The section about description and helpful suggestions on different Tibet an meditation techniques were super helpful and easy to understand and apply to one's meditation practice.
