Chogyal Namkhai Rinpoche was the first Vajrayana Master that started teaching Dzogchen in the West.
He wrote numerous books (commentaries, revealed teachings, instructions etc.) on the subject of Tantra and Dzogchen.
In 1976, Namkhai Norbu began to give Dzogchen instruction in the West, first in Italy, then in numerous other countries. He quickly became a respected spiritual authority among many practitioners and has created centers for the study of Dzogchen worldwide.
On 10 September 2018, the Italian government gave its highest award, Commander of the Order of Merit of the Italian Republic, to him from President Sergio Mattarella.
The Tibetan government in exile regarded him as having been “the foremost living Dzogchen” teacher at the time of his death in 2018.
