 In sum, the understanding of the nondual nature of the mind is obtained suddenly but the complete eradication of practical evils is achieved only gradually. Chinul also developed his scheme of Sudden Enlightenment to our true nature under the guise of emptiness followed by a Gradual Cultivation. Chinul, as a good Korean Buddhist monk, thus shows a nice syncretistic attitude toward the controversy known as Tonjŏm (頓漸) debate, suggesting a moderate position of tono chŏmsu 頓悟漸修 (gradualism, i.e., sudden enlightenment followed by gradual cultivation) (Chinul-CW, “Secrets on Cultivating the Mind”, 143) in contrast to, e.g., tono tonsu 頓悟頓修 (subitism, i.e., sudden enlightenment followed by sudden cultivation) (Peter H. Lee 1993, Vol. I, 418–419).
