Inspirational Quotes on Invincibility

“Invincibility depends on one's self; the enemy's vulnerability on him. It follows that those skilled in war can make themselves invincible but cannot cause an enemy to be certainly vulnerable. Therefore it is said that one may know how to win, but cannot necessarily do so.”

“It is a doctrine of war not to assume the enemy will not come, but rather to rely on one's readiness to meet him; not to presume that he will not attack, but rather to make one's self invincible.”
