Drepung, in Tibetan, means “prosperity”. Since its establishment, Drepung Monastery has always been one of the most important Buddhist monasteries in Tibet. In its heyday, there were more than 10,000 monks lived and studied in the monastery. Throughout its history, many important and famous Tibetan leaders used to study here, especially the Dalai Lamas. So Drepung Monastery is also respectfully known as the “Mother School of Dalai Lamas”.
