（1） The 'middle way，' a common term for the Buddhist path. In the earlier Pali literature it refers to a path that avoids the extremes of asceticism and self-satisfaction. （2） Later， during the development of Maha^ya^na Buddhism， especially as taught by Na^ga^rjuna 龙树 and others， it refers to the cultivation of the enlightened mindfulness which is not trapped in the extremes of nihi^ism or eternalism， or being and non-being. Also used as an informal term to refer to the Ma^dhyamika 中观派 school， which was founded by Na^ga^rjuna.（3） During the latter Silla in Korea， a school named Chungdo arose from somewhat uncertain origins， but which was not associated with the Sanlun school.
