Trisong Detsen
The "Skar-cung" pillar erected by Sadnalegs (ruled c. 800-815) says that during the reign of Trisong Detsen, "shrines of the Three Jewels were established by building temples at the centre and on the borders, "Bsam-yas" in "Brag-mar" and so on". The first edict of Trisong Detsen already mentions a community of monks at "Bsam-yas" (Samye), consisting of the former army.
