The monasteries of the different religious traditions of Tibet are represented on this map. The traditions, sometimes called sects, represent distinct lineages of teachers and teachings in the Tibetan Buddhist and Bon religions. The affiliations of some monasteries changed over time, and this map only represents the affiliation of monasteries in the 20th century. Some interesting patterns are revealed by this sort of visual representation. For instance, the dominance of the Gelukpa tradition in Amdo is very clear, while the core parts of Kham and Golok are equally clearly dominated by the Nyingma tradition. In contrast, the Bon and Kagyu traditions are better represented at the margins of Tibet or between major regional areas (e.g. note the line of Bon monasteries running from the northwest to the southeast between Kham and Central Tibet).
