Chögyam Trungpa Rinpoche (February 28, 1939 – April 4, 1987) the author of Meditation in Action was a Buddhist meditation master who founded Vajradhatu and Naropa University and establishing the Shambhala Training method.
He was the holder of both the Kagyu and Nyingma lineages, the eleventh Trungpa tülku, a tertön, supreme abbot of the Surmang monasteries, scholar, teacher, poet, artist, and originator of a radical re-presentation of Shambhala vision.
Recognized both by Tibetan Buddhists and by other spiritual practitioners and scholars as a preeminent teacher of Tibetan Buddhism, he was a major, albeit controversial, figure in the dissemination of Tibetan Buddhism to the West.
Among his contributions are the translation of a large number of Tibetan texts, the introduction of the Vajrayana teachings to the West, and a presentation of the Buddhadharma largely devoid of ethnic trappings.
Regarded as a mahasiddha by many senior lamas, he is seen as having embodied the crazy wisdom (Tib. yeshe chölwa) tradition of Tibetan Buddhism.
Some of his teaching methods and actions were the topic of controversy during his lifetime and afterwards.
