Invincibility is in oneself, and vulnerability is in the opponent. Invincibility is a matter of defense, vulnerability is a matter of attack. Therefore skillful warriors are able to be invincible, but they cannot cause opponents to be vulnerable. That is why it is said that victory is discerned and not manufactured.
Sun TzuThe clever combatant imposes his will on the enemy, but does not allow the enemy's will to be imposed on him.
Sun TzuA sovereign of high character and intelligence must be able to know the right man, should place the responsibility on him, and expect results.
