Ganden Tripa
He was born near Lhasa in 1543 and was recognised as the reincarnation of Gendun Gyatso and subsequently enthroned at Drepung Monastery by Panchen Sonam Dragpa, who became his tutor. Panchen Sonam Dragpa was the 15th Ganden Tripa and his texts still serve as the core curriculum for many Gelugpa monasteries. The third Dalai Lama studied at Drepung Monastery and became its abbot. His reputation spread quickly and the monks at Sera Monastery also recognised him as their abbot.
