In Gong Ye Chang of the Analects of Confucius, Zi Gong said, "What I do not wish men to do to me, I also wish not to do to men." The Master said, "Ci, you have not attained to that." of Zhu Xi's commentary, Zhu Xi given a point of view--the Difference of "Ren" and "Shu". The difference between the two is that "What you do not want done to yourself, do not do to others" (己所不欲,無施於人) and "What you do not want done to yourself, do not do to others" (己所不欲,勿施於人). There's only one word difference, namely, "Wu" (無) and "Wu" (勿). Through the "reverential feeling" (主敬) and "study the Principle" (窮理), can be raised from "Shu" to "Ren".
