Sanga Monastery is a small Buddhistmonastery located in the vicinity of Lhasa, Tibet. Sanga or Sangha is a word in Sanskrit that can be translated roughly as monastic "association" or "assembly" - possessing some high degree of realization, referred to as the arya-sangha or 'noble sangha'. Sanga Monastery was built amid the ruins of the castle (or fort) Taktse (also Dagtse) Dzong (formerly Dechen Dzong) on the hill top. Dagtse Dzong overlooks the roads to Yerpa and Ganden Monastery on the east.
At the roof of Sanga Monastery - Dhvarja (Skt., Rgyal-mtshan, Tib) symbolizing Buddha's victory over all anger and aggression, on the backgroung the sky of Himalayas.
Sanga Monastery together with Ganden Monastery belong to the Geluk (Gelug-pa) order (also known as Yellow Hat Sect, lit. 'Virtuous'). The Yellow Sect rose and prospered primarily because of the personal prestige of its founder Tsongkhapa (Tsong Khapa or Lobsang Drakpa, also known as Jé Rinpoché, 1357–1419) who is identified as the manifestation of Mañjushri, bodhisattva of Wisdom. He earned a high reputation as a writer and teacher, and was later warmly received in the Lhasa region. He was strongly scholastic in orientation, and encouraged the study of the great Indian masters of philosophy and logic: Nagarjuna, Asanga, Dignaga, et al.. In 1409 Tsongkhapa founded his first monastery, Ganden Monastery. The two other great monasteries were later founded, Drepung in 1416 and Sera in 1419. Several of his disciples were able to evolve in distinct school separate from Geluk. From those disciples also came the line of Dalai Lamas such as the 2nd Dalai LamaGendun Gyatso (see the statue of His Holiness The Fifth Dalai Lama Lobsang Gyatso in Sanga Monastery on your left).
In the 16th century the Geluk-school begun its rise to political preeminence when it came to enjoy the favor of a new generation of Mongolkhans. In 1642, Gursi Khan installed Ngawang Lobsang Gyatso (1617–1682), the Fifth Dalai Lama, as virtual leader of Tibet under overall Mongol protection.
