Dorji Wangchuk [Prof. Dr.] (born 1967) is the professor for Tibetan (Buddhist) Studies at the Department of Indian and Tibetan Studies, Asien-Afrika-Institut, Universität Hamburg, Germany, and is a contemporary Tibetologist and a Buddhologist.  After completing a nine-year course in the study of Tibetan Buddhism from a traditional Tibetan Buddhist monastic seminary in South India (i.e. sNga-’gyur-mtho-slob-mdo-sngags-rig-pa’i-’byung-gnas-gling, Bylakuppe, Mysore), Dorji Wangchuk studied Classical Indology (first major, with a focus on Buddhist Studies) and Tibetology (second major) at the Universität Hamburg (MA 2002).  He wrote his doctoral dissertation on “The Resolve to Become a "Buddha": A Study of the "Bodhicitta" Concept in Indo-Tibetan Buddhism” and received his PhD from the same University in 2005.  Between 1992 and 1996, he taught Tibetan Buddhist monks and nuns in monastic seminaries in India.  Since 1998, he has been teaching and researching at the Universität Hamburg in various capacities.  He also taught a term each at the University of Copenhagen, McGill University, and Renmin University of China.  Currently he is a professor for Tibetology (“Tibetan (Buddhist) Studies”) at the Department of Indian and Tibetan Studies, Asien-Afrika-Institut, Universität Hamburg.  He is also the founder and director of the Khyentse Center for Tibetan Buddhist Textual Scholarship (KC-TBTS), a research center within the Department of Indian and Tibetan Studies, Asien-Afrika-Institut, Universität Hamburg.  His main teaching and research interests lie in Tibetan Buddhist philosophy, Tibetan intellectual history and history of ideas, and Tibetan Buddhist intellectual/literary/textual culture.  Currently he is working on the perception and reception of Yogācāra in Tibet and on the identity, superiority, and authenticity issues of the "Vidhyādharapiṭaka" in Tibetan Buddhism. The Three Roots (Tibetan: "tsa sum") of the Tibetan Buddhist tradition are the lama (Sanskrit: "guru"), yidam (Sanskrit: "ishtadevata") and protector, which may be a "khandroma" (Sanskrit: "dakini") or "chokyong" (Sanskrit: "dharmapala").  The Three Roots are the second of three Tibetan Buddhist refuge formulations, the "Outer", "Inner" and "Secret" forms of the Three Jewels.  The 'Outer' form is the 'Triple Gem', (Sanskrit:"triratna"), the 'Inner' is the Three Roots and the 'Secret' form is the 'Three Bodies' or trikaya of a Buddha.  These alternative refuge formulations are employed by those undertaking Deity Yoga and other tantric practices within the Tibetan Buddhist Vajrayana tradition as a means of recognizing the universality of Buddha Nature.  The Three Roots are commonly mentioned in the Nyingma and Kagyu literature of Tibetan Buddhism.  Unlike most aspects of Tibetan Buddhism, which originated in India, the Three Roots may be an original Tibetan formulation from the time of Padmasambhava.  The functions of the Three Roots are: Tender Fictions is a 1996 autobiographical documentary film directed by American experimental filmmaker Barbara Hammer.

La Soufrière – Warten auf eine unausweichliche Katastrophe ("La Soufrière – Waiting for an Inevitable Disaster") is a 1977 West German documentary film in which German director Werner Herzog visits an island on which a volcano is predicted to erupt.  The pretext of this film was provided when Herzog "heard about the impending volcanic eruption, that the island of Guadeloupe had been evacuated and that one peasant had refused to leave, [he] knew [he] wanted to go talk to him and find out what kind of relationship towards death he had" (Cronin).  Herzog explores the deserted streets of the towns on the island.  The crew of three treks up to the caldera, where clouds of sulfurous steam and smoke shift drift like "harbingers of death" (Peucker), an example of the sublime Herzog seeks to conjure in his films.  Herzog converses in French with three different men he finds remaining on the island: one says he is waiting for death, and demonstrates his posture for doing so; another says he has stayed to look after the animals.  In the end, the volcano did not erupt, thus sparing the lives of those who had remained on the island, including Herzog and his crew. Grizzly Man is a 2005 American documentary film by German director Werner Herzog.  It chronicles the life and death of bear enthusiast Timothy Treadwell.  The film includes some of Treadwell's own footage of his interactions with grizzly bears before 2003, and of interviews with people who knew, or were involved with Treadwell, as well as professionals dealing with wild bears. Wheel of Time is a 2003 documentary film by German director Werner Herzog about Tibetan Buddhism.  The title refers to the Kalachakra sand mandala that provides a recurring image for the film. The Bureau of Buddhist and Tibetan Affairs, or Xuanzheng Yuan () was a government agency and top-level administrative department set up in Khanbaliq (modern Beijing) that supervised Buddhist monks in addition to managing the territory of Tibet during the Yuan dynasty (1271-1368) established by Kublai Khan.  It was originally set up in 1264 as an autonomous office named Zongzhi Yuan () or the Bureau of General Regulation, before it was renamed in 1288, which was named after the Xuanzheng Hall where Tibetan envoys were received in the Tang dynasty.  In the Mongol Empire, Tibet was managed by the Bureau of Buddhist and Tibetan Affairs, separate from the other provinces of the Yuan dynasty such as those governed the former Song dynasty of China, but still under the administrative rule of the Yuan.  While no modern equivalents remain, the political functions of the Bureau of Buddhist and Tibetan Affairs might have been analogous to the India Office in London during the British Raj.  Besides holding the title of Imperial Preceptor or Dishi, Drogön Chögyal Phagpa, the fifth leader of the Sakya school of Tibetan Buddhism, was concurrently named the director of the Bureau of Buddhist and Tibetan Affairs.  One of the department's purposes was to select a "dpon-chen" ('great administrator', a civilian administrator who governed Tibet when Sakya Lama was away), usually appointed by the lama and confirmed by the Mongol emperor in Beijing.  Tibetan Buddhism was not only practiced within the capital Beijing but throughout the country.  Apart from Tibetan affairs, the Bureau of Buddhist and Tibetan Affairs managed the entire Buddhist clergy throughout the realm (whether they were Han Chinese, Tibetan or Korean etc.), and supervised all temples, monasteries, and other Buddhist properties in the empire, at least in name.  According to scholar Evelyn Rawski, it supervised 360 Buddhist monasteries.  To emphasize its importance for Hangzhou, capital of the former Southern Song dynasty and the largest city in the Yuan realm, a branch (行, "Xing", "acting") Xuanzheng Yuan was established in that city in 1291, although Tibetan Buddhism took public or official precedence over Han Chinese Buddhism.
