Jigten Sumgön or Jigten Gönpo འཇིག་རྟེན་གསུམ་མགོན (1143–1217) was the founder of the Drikung Kagyu lineage and main disciple of Phagmo Drupa. He founded Drikung Thil Monastery in 1179. Jigten Sumgön and the Drikung lineage are best known for the set of teachings known as The Five Profound Paths of Mahāmudrā (phyag chen lnga ldan). Some of Jigten Sumgön's sayings were collected by Sherab Jungne into what is known as the Drikung Gongchig (Wylie transliteration: dgongs gcig, "the single intention"), a profound philosophical compendium that further developed in commentarial works written in following generations. Some of Jigten Sumgön's teachings were collected by another disciple into what is known as The Heart of the Great Vehicle's Teachings (theg chen bstan pa'i snying po). Life The meaning of Jigten Sumgön ('jig rten gsum mgon) is "The Lord of the Triple World". Jigten Sumgön is known under various names: Drikung Kyobpa Jigten Gönpo Rinpoche, Drikung Kyobpa Jikten Gönpo Rinchen Päl, Lord Jigten Sumgön, Kyobpa Rinpoche, and many others.

Jigten Sumgön was born in 1143 into a famous clan called the Kyura (skyu ra) in the Kham (khams) region of Tibet by the name of Tsungu (tsu ngu); his mother was Rakyisa Tsunma, and his father, Naljorpa Dorje, was a devout Vajrayāna practitioner (of Yamāntaka) who died when Jigten Sumgön was still a boy—at that time, Jigten Sumgön started to support his family by reciting scriptures. It is said that when he was only eight years old, he understood that all phenomena are like a reflection in a mirror. Due to his fame, many great masters came to study and practice in Drikung Thil for many centuries after Lord Jigten Sumgön's passing into parinirvāṇa. Perhaps the most famous of these was Lama Tsongkhapa, the founder of the Gelug school of Tibetan Buddhism. While staying near Drikung Thil, Tsongkhapa received the Drikung teachings on the Six Yogas of Naropa, as well as all of the outer and inner texts by Jigten Sumgön. Many Gelugpas, including the fourteenth Dalai Lama, uphold Tsongkhapa's lineage of Naropa's yogas until today.
