Ralung Monastery (Wylie: ra lung dgon), located in the Tsang region of western Tibet south of Karo Pass, is the traditional seat of the Drukpa Lineage of Tibetan Buddhism. It was founded in 1180 by Tsangpa Gyare, 1st Gyalwang Drukpa, a disciple of Lingje Répa (Wylie: gling rje ras pa) who founded the Drukpa Lineage.
Ralung is one of the most sacred places in Tibet, for it is here that the great Dugpa school of red-hat monks originated, a school still influential with numerous adherents in Southern, Northern, and Eastern Tibet, and in Bhutan, which latter country is, in fact, called Dugpa owing to the preponderance of this sect. The Ralung-til, the head monastery of the Dugpa, is to the south-east of this village. This monastery owes its name to the fact that it is surrounded by mountains as the heart (mt'il) of a lotus is by the corolla.
The monastery is located in present-day Gyantse county several kilometers south of the road connecting Nakartse and Lungmar, immediately north of the Gasa district of Bhutan. In previous times, trade could be conducted across the Yak La pass across the high Himalayas, extending the influence of Ralung to the south.
The monastery is surrounded by the towering peaks and glacier fields of Gyetong Soksum (6,244m), Jangzang Lhamo (6,324m) and Nojin Gangzang (7,191m). From the beginning the location was recognized as especially auspicious:
The eight auspicious symbols adorned the surrounding: The mountain in front of the monastery appeared in the form of a white conch turning clock-wise; the peak of Rala pass appeared like a precious open parasol; the peak behind Pokya appeared like a brimming vase; the Tsenchu peak appeared like a victory banner hoisted high; the Yangon hill appeared like a pair of golden fish; the ground at Gormo appeared like a golden wheel; the hill in the direction of Penthang appeared like an open lotus stem with the twin streams appearing like two birds facing each other; and Gyamo meadow appeared like an auspicious knot.
