Rimé movement
While the Indian texts are often central, original material by key Tibetan scholars is also widely studied and collected into editions called "sungbum". The commentaries and interpretations that are used to shed light on these texts differ according to tradition. The Gelug school for example, use the works of Tsongkhapa, while other schools may use the more recent work of Rimé movement scholars like Jamgon Kongtrul and Jamgon Ju Mipham Gyatso.
