Rinchen Gyaltsen served for a time as chaplain (
lacho) to Kublai Khan. However, when his brother Chakna Dorje died in 1267, this led to serious unrest as the important
Drigung Monastery tried to push back the position of Sakya. When his other brother Phagpa left Sakya and temporarily settled in
Amdo in the same year, Rinchen Gyaltsen took over as a "quasi-abbot" (
dansa tawu) of the Sakya Monastery. Phagpa arrived to the imperial court in
Beijing in 1370 and was appointed
Dishi (
Imperial Preceptor); however, he renounced the title in 1274 in order to return to Sakya. Instead, Rinchen Gyaltsen was summoned the court to fill the post in the same year. As imperial preceptor he resided in the palace compound Metog Rawa (Flowery Enclosure), as his brother had done. There he gathered a community of clerics. During his tenure the worldly affairs of Tibet were handled by a succession of administrators in Sakya, called
dpon-chen (
ponchen). They were: • Shakya Zangpo (c. 1264–1270) • Kunga Zangpo (c. 1270–1275) • Zhangtsun (c. 1275-?) • Chukpo Gangkarwa (?-1280) Rinchen Gyaltsen died in
Shingkun (Lintao) at an uncertain date, most probably 24 March 1279. According to another chronicle he died as late as 1282, which seems to be incorrect. He was succeeded as
tishri by his nephew
Dharmapala Raksita, a son of the viceroy Chakna Dorje. ==See also==
