“While Korean Buddhism did not begin as an exclusively Sŏn tradition, Sŏn was introduced into Korea perhaps as early as the late seventh century during Ch'an's incipiency on the Chinese mainland. By the thirteenth century, Sŏn came to dominate Buddhist doctrine and praxis, virtually eclipsing all other branches of Korean Buddhism after the fifteenth century.” SonKorean Buddhism Book:The Zen Monastic Experience Source: The Zen Monastic Experience
