窃谓夫为将者，能去能就，能柔能刚；能进能退，能弱能强。不动如山岳，难测如阴阳；无穷如天地，充实如太仓；浩渺如四海，眩曜如三光。预知天文之旱涝，先识地理之平康；察阵势之期会，揣敌人之短长。

73 "The Prime Minister of Han, Zhuge Liang, to the Minister of War, Cao Zhen:
74 "You will permit me to say that a leader of an army should be able to go and come, to be facile and obdurate, to advance and retire, to show himself weak or strong, to be immovable as mountains, to be inscrutable as the operations of nature, to be infinite as the universe, to be everlasting as the blue void, to be vast as the ocean, to be dazzling as the lights of heaven, to foresee droughts and floods, to know the nature of the ground, to understand the possibilities of battle arrays, to conjecture the excellencies and defects of the enemy.
