Mangong Wolmyeon

Mangong Wolmyeon (1872–1946) was one of the three great disciples of Gyeongheo Seongu and the master most responsible for maintaining rigorous Seon meditation standards during the turbulent period of Japanese colonial rule over Korea. He entered monastic life at age thirteen and studied under Gyeongheo, whose unconventional methods pushed Mangong to the depths of hwadu practice. His awakening came after years of intense struggle with the koan "The problem of the problem is the problem" — a characteristically paradoxical formulation of Gyeongheo's.

During the Japanese occupation (1910–1945), when colonial authorities attempted to reshape Korean Buddhism along Japanese lines — permitting married clergy and consolidating temples under Japanese administrative control — Mangong was among the most resolute defenders of traditional Korean monastic discipline. He insisted on celibacy, strict precept observance, and intensive meditation retreat practice, resisting the "Japanification" of Korean Buddhism. He trained many important students, including Gobong Gyeonguk, who would become the teacher of Seung Sahn. Mangong's fierce commitment to the integrity of the Korean Seon tradition during its most vulnerable period ensured that authentic practice survived to be transmitted to the postcolonial generation.
