Tibetan Buddhist schools There are various schools or traditions of Tibetan Buddhism. The four main traditions overlap markedly, such that "about eighty percent or more of the features of the Tibetan schools are the same". Differences include the use of apparently, but not actually, contradictory terminology, opening dedications of texts to different deities and whether phenomena are described from the viewpoint of an unenlightened practitioner or of a Buddha. On questions of philosophy, there has historically been disagreement regarding the nature of Yogacara and Buddha-nature teachings (and whether these are of expedient meaning or ultimate meaning), which still colours the current presentations of sunyata (emptiness) and ultimate reality. The 19th century Rimé movement downplayed these differences, as still reflected in the stance of the Fourteenth Dalai Lama, who states that there are no fundamental differences between these schools. However, there are still philosophical disagreements between the different traditions, such as the debate regarding rangtong and shentong interpretations of Madhyamaka philosophy. The four major schools are sometimes divided into the Nyingma (or "Old Translation") and Sarma (or "New Translation") traditions, which follow different canons of scripture (the Nyingma Gyubum along with Termas and the Tengyur-Kangyur respectively). Each school also traces itself to a certain lineage going back to India as well as certain important Tibetan founders. While all the schools share most practices and methods, each school tends to have a certain preferred focus (see table below).
