Kanchi Sosan

The thirtieth patriarch, [China's Third Patriarch,] was Great Master Chien-chih [Seng-ts'an]. He visited the twenty-ninth patriarch and said, "My body is infected with leprosy I beg you, O priest, to cleanse me of my wrongdoing." The Patriarch said, "Bring me your wrongdoing and I will cleanse you." The master paused awhile and then said, "When I look for my wrongdoing, I cannot find it." The Patriarch replied, "I have already cleansed you of your wrongdoing. You must rely on the Buddha, Dharma, and Community of believers."
