Shakya Yeshe, Jamchen Choje (1354-1435 [TBRC P3450]), became one of the principal students of Je Tsongkapa when he was between the age of 45 to 50 years. Prior to that he studied according to the Kagyu system of Tsel Gungtang. He journeyed to Nanjing to see the Yongle emperor of China. Shakya Yeshe arrived in Nanjing in 1408 (according to some accounts, others 1415) and remained there until 1418. He founded the Sera Monastery in Lhasa in 1419. Shakya Yeshe again returned to China in 1424 and remained at the court (now moved since 1410 to Beijing) until 1435.
