The rDzogs chen teachings are found in the two oldest spiritual traditions of Tibet: the Bön and the rNying ma school of Buddhism. Research carried out on this teaching system over the next five-year programme will be based on the study of one of the most influential textual collections of the whole history of rDzogs chen: sNying thig ya bzhi. This collection consists of a set of five corpora belonging to the Most Secret Cycle (yang gsang) of the Section of the Precepts (Man ngag sde): 1. The Bi ma snying thig (3 volumes, end of the 10e c.), 2. The Bla ma yang tig (2 volumes, of Klong chen pa, 1308-1364), 3. The mKha’ ‘gro snying thig (2 volumes, 14e c), 4. The mKha’ ‘gro yang tig (3 volumes, of Klong chen pa), and 5. A summary of the set in the Zab mo yang tig (2 volumes of Klong chen pa). The aim of this program is to give an analysis of these five corpora (spanning a total of 11 volumes), with a preliminary catalogue, a systematic description of all the texts that compose it, and a translation of the biographies of the most important figures associated with this collection. Sources that predate the collection and later sources based on it will also be examined and translated selectively.

This project will examine Bon rituals from two different perspectives. The first is textual, with a corpus of texts that will be selected for study and its contents rendered accessible through reproduction, paraphrase and translation. A compilation of ritual texts consisting of 890 folios subdivided into a hundred sections will constitute the project’s core corpus although other canonical and non-canonical Bonpo material will also be studied. An important part of the project’s textual component will be to study collections of Bonpo manuscripts in collaboration with the Centre for Manuscript Studies of the University of Hamburg in order to identify distinctive codicological features that might be typical of Bonpo texts. The project’s second aspect deals with ritual performance. Special attention will be given to the activities of priests or monks and their assistants; the participation of non-specialists will also be taken into consideration. It is possible to follow the development of the project on a dedicated website ( where images and texts are linked to subtitled video recordings.
