Ever since national master Do-ui brought the method of Seon practice from China in the Silla Danasty, the Nine Schools of Korean Seon arose and fell, finally integrating into the Jogye Order. The lineage of Korean Seon initiated by national master Bojo and Taego in the Goryeo Dyanasty originated from the Southern Chan of China. It is generally considered that the Korean Seon method succeeded Da-hui who belonged to the Yang-qi branch of the Lin-ji school. Da-hui Chan penetrated intellectuals after the Yuan and Ming Dynasty in China and became the driving force of the Chan movement. Likewise, Taego Seon was the engine of integration for all the Buddhist sects into Seon-centered Korean Buddhism. Taego introduced the Lin-ji school to later stagnant Goryeo Buddhism through the cultivation of One Mind. Thus, Ganhwa Seon played a key role in transmitting the lamp of the patriarchs and became a significant energy of the Jogye Order`s tradition. The practice of Ganhwa Seon as an initial enlightenment, which has faith in `the original purity of mind` is a kind of short-cut practice that returns to the original sources of innate enlightenment. Ganhwa Seon regards `a big faith` and `a big doubt` as it`s essence and is a vital mainspring of Korean Seon.
