A warrior who is prepared to fight must also be prepared to die.

To perceive victory when it is known to all is not really skilful. Everyone calls victory in battle good, but it is not really good.

If a battle can not be won do not fight it.

Hence the saying: One may know how to conquer without being able to do it.

If soldiers are punished before they have grown attached to you, they will not prove submissive; and, unless submissive, then will be practically useless. If, when the soldiers have become attached to you, punishments are not enforced, they will still be unless.

If you know yourself but not the enemy, for every victory gained you will also suffer a defeat.

Appear weak when you are strong, and strong when you are weak.
