Sullivan, Brenton (2020), Building a Religious Empire: Tibetan Buddhism, Bureaucracy, and the Rise of the Gelukpa, University of Pennsylvania Press, pp. 37–38, ISBN978-0-8122-5267-5: "During this pivotal period of the fifteenth and sixteenth centuries, [Gyelwang Karmapa's] power was manifest in his Great Encampment, garchen in Tibetan. The garchen's influence included even outposts in Ngari of far western Tibet and it maintained a significant presence at the major pilgrimage site of Tsari, or Crystal Mountain, along the border with Arunachal Pradesh."
Chakraverty, Anjan (1998), Sacred Buddhist Painting, Lustre Press, p. 66, ISBN978-81-7436-042-7: "Karmapa lamas who used to be on the move constantly lived in large tent cities with great pomp. The mobile Karmapa encampments were known as Karma Garchen and thus the style patronised in the encampments was labelled the Karma Gadri style (the style of the Karma encampment)."
