Sera Monastery in the context of "Bhavachakra"

The 3rd Dalai Lama, Sonam Gyatso (Tibetan: བསོད་ནམས་རྒྱ་མཚོ་, Wylie: bsod nams rgya mtsho, ZWPY: Soinam Gyaco; 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.

Ganden Monastery (also Gaden or Gandain) or Ganden Namgyeling or Monastery of Gahlden is one of the "great three" Gelug university monasteries located in Dagzê County, Lhasa, Tibet. The other two are Sera Monastery and Drepung Monastery. Ganden Monastery was founded in 1409 by Je Tsongkhapa Lozang-dragpa, founder of the Gelug order. The monastery was destroyed after 1959, but has since been partially rebuilt. Another monastery with the same name and tradition was established in Southern India in 1966 by Tibetan exiles.

The Tibetan Buddhist canon is a compilation of the Buddhist sacred texts recognized by various schools of Tibetan Buddhism. The Canon includes the Kangyur, which is the Buddha's recorded teachings, and the Tengyur, which is commentaries by great masters on the Buddha's recorded teachings. The first translation into Tibetan of these manuscripts occurred in the 8th century and is referred to as the Ancient Translation School of the Nyingmas.

The Tibetan Canon underwent another compilation in the 14th century by Buton Rinchen Drub (1290–1364). Again, the Tibetans divided the Buddhist texts into two broad categories:
