Know thy self, know thy enemy. A thousand battles, a thousand victories.

For to win one hundred victories in one hundred battles is not the acme of skill. To subdue the enemy without fighting is the acme of skill.

For to win one hundred victories in one hundred battles is not the acme of skill. To subdue the enemy without fighting is the acme of skill.

If you know the enemy and know yourself you need not fear the results of a hundred battles.

Know your enemy and know yourself and you can fight a hundred battles without disaster.

To fight and conquer in all our battles is not supreme excellence; supreme excellence consists in breaking the enemy's resistance without fighting.
