Gedun Gyatso was a renowned scholar and composer of mystical poetry, who traveled widely to extend
Gelugpa influence, and became
abbot of the largest Gelugpa monastery, Drepung, which from this time on was closely associated with the reincarnation line which eventually would be known as that of the Dalai Lamas. According to Sumpa Khenpo, the great
Gelug scholar, he also studied some
Nyingma-pa
tantric doctrines. It is said that Palden Lhamo, the female guardian spirit of the
sacred lake,
Lhamo Latso, promised the First Dalai Lama in one of his visions "that she would protect the reincarnation lineage of the Dalai Lamas." Since the time of Gendun Gyatso, who formalised the system, monks have gone to the lake to seek guidance on choosing the next reincarnation through visions while meditating there. Gendun Gyatso is said to have been the first to discover the sacredness of Lake Lhamo Latso. Gedun Gyatso became abbot of Tashilhunpo in 1512 at the age of thirty-six. In 1517 he became abbot of
Drepung monastery and he revived the 'Great Prayer Festival' or
Monlam Chenmo in 1518, presiding over the celebration with monks from the three large Gelug monasteries of
Sera, Drepung and
Gaden (Ganden was the original monastery of the Geluk order, founded by Je Tsongkhapa himself in 1409). He then became abbot of
Sera monastery in 1525; Sera had been founded in 1419, by Jamchen Chojey (Sakya Yeshe), a disciple of Tsong Khapa. His Seat has been Drepung. Gedun Gyatso died deep in meditation at the age of 67 in 1542. ==References==
