The story of Korean Seon unfolds across many generations, with certain figures standing out as pivotal in shaping its character. Early on, masters such as Doui are remembered for bringing Chan teachings from China and establishing influential lineages like the Gaji-san school, which became one of the Nine Mountain Seon traditions. Other founders of these mountain schools, including Beomil of the Sagul-san school, Hongcheok of the Dongli-san school, Hyeneung of the Gajisan school, and Muyeom of the Seongju school, helped root Seon deeply in Korean soil by creating distinct practice communities. Their efforts collectively formed a network of Seon centers that localized imported Chan methods into a Korean context.

As the tradition matured, figures such as Jinul emerged as systematizers and unifiers. Jinul is often regarded as the most influential master in Korean Seon history, known for synthesizing meditative practice with doctrinal study and for advocating the integration of gyo (doctrine) and seon (meditation). His work at Songgwangsa monastery turned it into a major center of Seon practice and laid the foundations for what became known as the Jogye Order. Later, Taego Bou further strengthened and revitalized Seon, particularly through his engagement with Chinese Zen and his role in consolidating the Jogye lineage as the primary Seon tradition.

Subsequent centuries saw continued reinterpretation and defense of Seon within changing cultural and intellectual climates. During the Joseon period, Hyujeong (also known as Seosan Daesa) and Gihwa (Hamheo Deuktong) are remembered for revitalizing Korean Buddhism in an era dominated by Confucian thought, preserving Seon’s contemplative heart while articulating it in dialogue with prevailing philosophies. In more recent times, masters such as Mangong, Kusan Sunim, and Seongcheol have been seen as key figures in the modern revival of Korean Seon, emphasizing rigorous practice and maintaining continuity with classical teachings. Taken together, these teachers form a living lineage in which meditation, doctrinal reflection, and adaptation to historical circumstances are woven into a single, continuous thread.
