Seungsahn was a Korean-born Zen Buddhist master who played a major role in transmitting Seon (Korean Zen) to the United States and internationally. As founder of the Kwan Um School of Zen, he established a network of temples, centers, and practice groups that connected Zen Buddhism traditions across Asia, Europe, and the Americas. Known for accessible teaching methods, kong-an practice, and a prolific correspondence with students, he became a prominent figure in late 20th-century Buddhist modernism and interreligious exchange.
Born in Sunch'ŏn, South Pyongan Province, then part of Chōsen (Korea), he was raised during the tumultuous period of Japanese rule in Korea and the Korean War. As a youth he entered monastic training at a local Korean Buddhist temple and later studied with modernist Korean literati such as Han Yong-un (Manhae), who linked Buddhist reform to Korean nationalism and literary movements. After ordination he engaged with traditional Seon curricula, training in monastery practice, chanting, and koan-style teaching found in lineages connected to figures like Bonghan Sunim and the revitalized Korean Seon establishment.
He received monastic ordination within the Korean Buddhist monastic system and underwent intensive practice in Korean Seon monasteries. During this period he studied with established Korean masters and eventually received dharma transmission, formalizing his recognition as a teaching lineage holder within the Korean transmission networks that also include figures associated with the Jogye Order and postwar reconstruction of Korean Buddhism. His transmission placed him in the stream of modern Korean Seon teachers who sought to engage Western seekers and global diasporas, paralleling contemporaries such as Seongcheol and international teachers like D.T. Suzuki in cross-cultural outreach.
After emigrating to the United States in the 1970s, he established the Providence Zen Center in Rhode Island and later expanded to create the Kwan Um School of Zen with affiliated centers in cities including Boston, New York City, Los Angeles, San Francisco, and international branches in Seoul, London, Paris, Berlin, Madrid, São Paulo, and Sydney. The school combined Korean Seon forms with institutional models familiar to Western practitioners, forming training programs, retreats (including kyolche-style sesshin), and teacher ordination procedures. Institutional development involved interaction with American religious infrastructure such as Harvard University-adjacent communities and intercultural dialogues seen in forums with representatives from Theravāda Buddhism, Tibetan Buddhism, and Christian monasticism.
His teaching emphasized direct pointing to mind, using kong-an (koan) practice adapted from Chinese Zen and Japanese Rinzai methods, alongside chanting and seated meditation drawn from Korean liturgy. He popularized succinct teaching phrases and practice devices—such as "Don't-Know Mind" and "Only Don’t Know"—designed to orient Western students toward nondual insight. Group practice integrated lecture, kong-an interviews, and communal work periods reminiscent of monastic practice in institutions like traditional Korean Seon monasteries and Japanese temples such as Eihei-ji. He also engaged with contemporary psychology and transpersonal discussions, dialoguing with figures from humanistic psychology and participating in exchanges with educators at institutions like Brown University and Tufts University.
He published collections such as The Whole World Is a Single Flower and numerous recorded dharma talks and kong-an commentaries distributed through the Kwan Um School and independent presses. His recorded teachings were often transcribed and circulated as lecture series and practice manuals used by centers across North America and Europe. Translations and publications appeared in cooperation with Buddhist publishers and academic studies of modern Buddhism, and his recorded archives contributed to oral-history projects examining the growth of Buddhism in the United States and the globalization of Asian religious movements.
Seungsahn and the Kwan Um School faced several controversies, including allegations of inappropriate behavior and leadership disputes that prompted internal investigations and public criticism during the late 20th and early 21st centuries. Critics and some former students raised concerns about power dynamics and accountability, paralleling broader critiques directed at other Westernized Buddhist communities such as those associated with Chögyam Trungpa and Sogyal Rinpoche. These disputes led to organizational reforms, public statements by Kwan Um governance bodies, and discussions in scholarly venues addressing ethics, teacher-student relations, and institutional oversight similar to debates in the American Buddhist landscape.
His legacy includes the global network of Kwan Um centers, the training of Western dharma teachers, and contributions to public awareness of Korean Seon practice in the West. Alumni of Kwan Um have established centers, written on practice, and engaged in interreligious dialogue with institutions such as The Parliament of the World's Religions and academic departments at Columbia University and University of California, Berkeley. His methods influenced contemporary Zen pedagogy alongside teachers from San Francisco Zen Center, Zen Center of Los Angeles, and other Western Zen lineages. Despite controversies, his role in transplanting Korean Seon into international contexts remains a significant chapter in the history of modern globalized Buddhism.
