The strength of walls depends on the courage of those who guard them.

The greatest pleasure is to vanquish your enemies and chase them before you, to rob them of their wealth and see those dear to them bathed in tears, to ride their horses and clasp to your bosom their wives and daughters.

I hate luxury. I exercise moderation…It will be easy to forget your vision and purpose one you have fine clothes, fast horses and beautiful women. [In which case], you will be no better than a slave, and you will surely lose everything.

Heaven grew weary of the excessive pride and luxury of China... I am from the Barbaric North. I wear the same clothing and eat the same food as the cowherds and horse-herders. We make the same sacrifices and we share.. our riches. I look upon the nation as a new-born child and I care for my soldiers as though they were my brothers.

Heaven is weary of the luxury of China. I shall remain in the wilderness of the north. I shall return to simplicity and moderations once again. As for the clothes I wear and the food I eat, I shall have the same as cowherds and grooms and I shall treat my soldiers as brothers. In a hundred battles I have been at the forefront and within seven years I have performed a great work, for in six directions of space all things are subject to one ruler.

A man's greatest moment in life is when his enemy lays vanquished, his village aflame, his herds driven before you and his weeping wives and daughters are clasped to your breast.

Not even a mighty warrior can break a frail arrow when it is multiplied and supported by its fellows. As long as you brothers support one another and render assistance to one another, your enemies can never gain the victory over you. But if you fall away from each other your enemy can brake you like frail arrows, one at a time.
