“Zen is not coextensive with any one school, whether that be Korean Sŏn or Japanese Rinzai Zen. There have actually been many independent strands of what has come to be called Zen, the sorting out of which has occupied scholars of Buddhism for the last few decades. These sectarian divisions are further complicated by the fact that there are Zen traditions in all four East Asian countries—China, Korea, Japan, and Vietnam—each of which has its own independent history, doctrine, and mode of practice. While each of these traditions has developed independently, all have been heavily influenced by the Chinese schools of Ch'an (Kor. Sŏn; Jpn. Zen; Viet. Thiên). We are therefore left with an intricate picture of several independent national traditions of Zen, but traditions that do have considerable synergy between them. To ignore these national differences would be to oversimplify the complicated sectarian scene that is East Asian Zen; but to overemphasize them would be to ignore the multiple layers of symbiosis between Zen's various national branches. These continuities and transformations between the different strands must both be kept in mind in order to understand the character of the "Zen tradition.” — Robert E. Buswell Jr.
