In warfare, first lay plans which will ensure victory, and then lead your army to battle; if you will not begin with stratagem but rely on brute strength alone, victory will no longer be assured.

It is the rule in war, if ten times the enemy's strength, surround them; if five times, attack them; if double, be able to divide them; if equal, engage them; if fewer, defend against them; if weaker, be able to avoid them.

Attack like the Fire and be still as the Mountain

He who is prudent and lies in wait for an enemy who is not, will be victorious.

He whose ranks are united in purpose will be victorious.

Know the enemy and know yourself; in a hundred battles you will never peril.

In desperate position, you must fight.
