Therefore, Dudjom Rinpoche was a poet, author, scholar and Vajrayana Master. He also organised the building of monasteries, and teaching and retreat centers, in India, Nepal, Bhutan, and other countries. Within the Nyingma School is the Dzogchen Lineage, or the "Great Perfection", in which the 14th Dalai Lama is also a lineage holder. He had received the teachings from two teachers, namely Dilgo Khyentse and Trulshik Rinpoche. Both of them were students of the second Dudjom Rinpoche, and holders of the Dzochen Lineage. In 1988, a year after his death, Dudjom Rinpoche's body was moved from France to Nepal, and placed in a stūpa in a main monastery near Boudhanath, Nepal.
