Hamho Tukt'ong （1376-1433）. Posthumous name Kihwa 己和. A late Koryo-early Choson monk of the Son order， who was the leading Buddhist figure of his generation. Hamho was originally a Confucian scholar of the highest reputation， but he converted to Buddhism at the age of 21 upon the death of a close friend. He wandered among the Korean mountain monasteries， until he had the fortune of becoming the disciple of the last Korean National Teacher Muhak 无学. Kihwa's writings showed a distinctive mixture between iconoclastic and suddenistic Chan language， and a strong appreciation for the scriptural tradition. Thus， he took up from Chinul the tradition of unification of Son and Kyo Buddhism. Among his writings， there are four works in particular that made a deep impact on the subsequent Son tradition in Korea. These are: （1） his commentary on the Su^tra of Perfect Enlightenment， the Won'gakkyong hae sorui 圆觉经解说谊; （2） his redaction and subcommentary to five famous earlier commentaries on the Diamond Sutra， the Kumgang panyaparamilgyong ogahae sorui 金刚般若波罗蜜经; （3） his subcommentary and redaction of the Collection of Yongjia， the Yonggajip kwaju sorui 永嘉集科注说谊. As a result of his fourth major work （4） the Hyonjong non 显正论 Hamho distinguishes himself as being the primary Buddhist respondent to the rising Neo-Confucian polemic of his period， as he responds with vigor to the Neo-Confucian criticisms of Buddhism. Hamho passed away while residing at Chongsu-sa 净水寺， located at the southern tip of Kanghwa Island 江华岛， where his tomb can still be visited. For a doctoral dissertation which analyzes Hamho's life and works see Muller （1993）; Hamho's commentary on the Sutra of Perfect Enlightenment is translated in Muller （1999）.
