Drepung Monastery is situated at the foot of the Mountain Gambo Utse, 5 kilometers from the western suburb of Lhasa, the Drepung Monastery is known as the most important monastery of Gelugpa in Tibetan Buddhism. For thirty-two years, the founder himself maintained the monastery as a great institution by giving extensive discourses on the Three Baskets with respect to sutra studies and on the four classes of tantra with respect to tantra studies. A great assembly of monks gathered who were interested in these excellent teachings and they divided themselves into seven groups, with each having its own teacher to give discourses. Thus, were established the seven great colleges of Gomang, Losel-ling, Deyang, Shagkor, Gyelwa or Tosamling, Dulwa, nd Ngagpa.
