《宋史·列传·卷二百零二》
只有深怀技艺与本领而又自爱的人才能无敌于天下。所以说，一忍可以应付百勇，一静可以制服百动。
夫惟养技而自爱者无敌于天下，故一忍可以支百勇，一静可以制百动。
Only those who are deeply skilled and capable and love themselves can be invincible in the world. Therefore, it is said that one patience can deal with a hundred brave men, and one calmness can control a hundred movements.
