 Gorampa Sonam Senge (Go rams pa bSod nams Seng ge, 1429–89) is one of the most widely-studied philosophers in the Sakya (sa skya) school of Tibetan Buddhism. A fierce critic of Tsongkhapa, the founder of what later came to be known as the Gelug (dge lugs) school, his works were so controversial that they were suppressed by Gelug leaders shortly after they were composed. Gorampa’s texts remained hidden until the early 20th century, when the monk Jamgyal Rinpoche received permission from the thirteenth Dalai Lama to collect Gorampa’s extant texts and have them reprinted in Derge. Today, Gorampa’s philosophy is studied widely in monastic colleges, not only in those affiliated with his own Sakya tradition, but also in institutions affiliated with the Kagyu (bka' brgyud) and Nyingma (rnying ma) schools.
