If fighting is sure to result in victory, than you must fight, even though the ruler forbid it; if fighting will not result in victory, then you must not fight even at the ruler’s bidding.
Move swift as the Wind and closely-formed as the Wood. Attack like the Fire and be still as the Mountain.
Do not press an enemy at bay.
Let your plans be dark and impenetrable as night, and when you move, fall like a thunderbolt.
To know your Enemy, you must become your Enemy.
Know yourself and you will win all battles.
Victory comes from finding opportunities in problems.
Know thy self, know thy enemy. A thousand battles, a thousand victories.
Keep your friends close, your enemies even closer.
The greatest victory is that which requires no battle.
If your opponent is of choleric temper, irritate him.
Quickness is the essence of the war.
