One who believes in himself has no need to convince others.

The generals have a saying: "Rather than make the first move it is better to wait and see. Rather than advance an inch it is better to retreat a yard." This is called going forward without advancing, pushing back without using weapons. There is no greater misfortune than underestimating your enemy. Underestimating your enemy means thinking that he is evil. Thus you destroy your three treasures and become an enemy yourself. When two great forces oppose each other, the victory will go to the one that knows how to yield.

Who is unhappy with little, won't be with much; who doesn't appreciate the small won't be able to take care of the large; who doesn't have enough with enough is at the margin or virtue, for the physical body lives from one day to another and if it gets what it really needs, there will be time for meditation, as long as if we try to give it everything it desires, endless will be the task.

Thus an army without flexibility never wins a battle. A tree that is unbending is easily broken.

Wary, as if surrounded by strangers.

There is no greater danger than underestimating your opponent.

Take time to listen to what is said without words, to obey the law too subtle to be written, to worship the unnameable and to embrace the unformed.
