Naong Hyegeun

Naong Hyegeun (1320–1376) was a leading Seon master of the late Goryeo dynasty who, along with his contemporary Taego Bou, played a crucial role in revitalizing Korean Buddhism through renewed contact with Chinese Chan. He traveled to Yuan China around 1347, where he studied under the Indian master Dhyanabhadra and received dharma transmission from Pingshan Chulin, a Linji lineage holder. During his time in China, he also gained the respect of the Yuan court and received imperial recognition.

Upon returning to Korea, Naong attracted a large following and was appointed Royal Preceptor by King Gongmin, who relied on him for both spiritual guidance and political counsel. He undertook the reform of monastic discipline and the revival of rigorous meditation practice at a time when Korean Buddhism had grown institutionally complacent. His most lasting legacy was his influence on subsequent generations through his many students, including Muhak Jacho, who would later serve as advisor to King Taejo, the founder of the Joseon dynasty. Naong's integration of scholarly breadth, contemplative depth, and political engagement exemplified the Korean ideal of the monk as both practitioner and public servant.
