1. 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).’
2. The soft overcomes the hard; and the weak the strong.
3. Fishes should not be taken from the deep; instruments for the profit of a state should not be shown to the people.
