Ganden Monastery
When he was 20 years old, in about 1411, he received the name Gedun Drupa upon taking the vows of a bhikṣu (monk) from the abbot of Narthang Monastery. Also at this age he became a student of the scholar and reformer Je Tsongkhapa (1357–1419), who some say was his uncle. Around this time he also became the first abbot of Ganden Monastery, founded by Tsongkhapa himself in 1409. By the middle of his life, Gedun Drupa had become one of the most esteemed scholar-saints in the country.
