, IsMEO, Rome, 1961 In the late 1950s, Norbu made a pilgrimage that took him to central Tibet, India, Bhutan, and Nepal. Because of the turmoil and aftermath of the
1959 Tibetan Rebellion, he could not return to Derge from Sikkim, so he stayed as a refugee in
Gangtok, working as a writer and editor of Tibetan literature for the
Chogyal government from 1958 to 1960. It was here that he met with the Italian
Tibetologist Giuseppe Tucci. Also during his time in Sikkim, he met and received teachings from the
XVI Gyalwa Karmapa. Already recognized as a knowledgeable figure in all aspects of Tibetan culture at the age of 22, Norbu was invited to Italy by Giuseppe Tucci to work at the Institute for the Middle and Far East () in Rome for two years. He collaborated with Tucci and Geshe Jempel Senghe on
a catalogue and library of Tibetan texts. In 1962, he took up a post in Naples at the
Istituto Universitario Orientale, where he taught the Tibetan language and literature until 1992. Namkhai Norbu focused his research on the ancient history of Tibet, the
Shang Shung kingdom, and the
Bön tradition. His research included works on history,
Tibetan medicine, astrology, Bön, and Tibetan folk traditions. Norbu married Rosa Tolli in 1968. They had a son, (born in 1970), and a daughter, Yuchen Namkhai (born in 1971). ==Teaching Dzogchen in the West==
