3rd Dalai Lama

The 3rd Dalai Lama, Sonam Gyatso (); (1543–1588) was the first in the tulku lineage to be entitled formally as the Dalai Lama. In 1578 Altan Khan presented the spiritual title of Dalai Lama, in honor of Sonam Gyatso's profound teachings conferred in Mongolia, which soon became a Tibetan Buddhist country. He founded Kumbum Monastery, Lithang Monastery, and Namgyal Monastery. The spiritual title was retrospectively given to his two tulku lineage predecessors, the 1st Dalai Lama and the 2nd Dalai Lama.

Sonam Gyatso 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 Gelug monasteries. The 3rd 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.

According to Sumpa Khenpo, the great Gelug scholar, he also studied Nyingma tantric doctrines.

When one of Tibet's regional kings, who had been supported by the Kagyu school, died in 1564, Sonam Gyatso presided over his funeral. His political power, and that of the Gelug school, grew in dominance in Tibet by the 1570s. Provided by Wikipedia
