One defends when his strength is inadequate, he attacks when it is abundant.

To maintain an army at a distance causes the people to be impoverished.

When envoys are sent with compliments in their mouths, it is a sign that the enemy wishes for a truce.

Should the enemy strengthen his van, he will weaken his rear; should he strengthen his rear, he will weaken his van; should he strengthen his left, he will weaken his right; should he strengthen his right, he will weaken his left. If he sends reinforcements everywhere, he will everywhere be weak.

Thus those skilled in war subdue the enemy's army without battle .... They conquer by strategy.

Victory is reserved for those who are willing to pay its price.

If it is to your advantage, make a forward move; if not, stay where you are.
