《吕氏春秋·纪·仲秋纪》
圣人一定把握自己的主动权，一定不依赖敌人的过失，所以，掌握着不可被战胜的策略，以此同可以战胜的敌人交锋，像这样，用兵就万无一失了。
圣人必在己者，不必在彼者，故执不可胜之术以遇不胜之敌，若此，则兵无失矣。
The wise general, therefore, makes his own arrangements, and does not rely on the mistakes of the enemy. Hence the saying: With a well-ordered host, await the disordered foe; then victory is certain.
