A ruler wishing to win should not trust a cunning enemy, even if he may be extending a hand of friendship. Because deep-rooted enmity, however, concealed, will surely come to light.

A debt should be paid off till the last penny; An enemy should be destroyed without a trace.

Till the enemy's weakness is known, he should be kept on friendly terms.

You must not fear death, my lads; defy him, and you drive him into the enemy's ranks.

A commander in chief ought to say to himself several times a day: If the enemy should appear on my front, on my right, on my left, what would I do? And if the question finds him uncertain, he is not well placed, he is not as he should be, and he should remedy it.

Love is the only force capable of transforming an enemy into friend.
