When one is about to take an inspiration, he is sure to make a (previous) expiration;
　　when he is going to weaken another, he will first strengthen him;
　　when he is going to overthrow another, he will first have raised him up;
　　when he is going to despoil another, he will first have made gifts to him:--
　　this is called 'Hiding the light (of his procedure).'
　　
　　The soft overcomes the hard; and the weak the strong.
　　
　　Fishes should not be taken from the deep;
　　instruments for the profit of a state should not be shown to the people.
