The aim of this typology of religions, sects, and sub-sects within Tibet and the Himalayas is to produce a simple scheme that can be used for typing sectarian affiliation for religious institutions, regions, and individuals in databases. Each will eventually have a summary of from a paragraph to a page of reference in terms of its history and characteristics. The scheme is not intended to be overly granular, and neglects how large monasteries themselves may have large networks of affiliated monasteries and temples that themselves form a coherent association.
