踏上德行之路，旧人必须克己， 但不要把新人置诸死地。 When taking the first steps on the road of virtue the old man must be mortified, but in such a way as not to slay the new man.

留意两种内、外的克己的分别： 前者是主要的，人应时常寻求的； 后者按照地点、人物及时间等处境衡量。

最好的克己是较尖锐的刺痛，伤害较小， 身体因此承受更大及持续的苦恼。 The best kind of mortifications are those that, while their sting is sharper, do less hurt: for by these the body is afflicted both more annoyingly and more lastingly.
