Dorje Shugden
The Dorje Shugden is a controversy over Dorje Shugden, also known as Dolgyal, who some consider to be one of several protectors of the Gelug school, the school of Tibetan Buddhism to which the Dalai Lamas belong. Dorje Shugden has become the symbolic centre-point of a conflict over the "purity" of the Gelug school and the inclusion of non-Gelug teachings, especially Nyingma ones.
