You can be sure of succeeding in your attacks if you only attack places which are undefended.You can ensure the safety of your defense if you only hold positions that cannot be attacked.

Thus, what is of supreme importance in war is to attack the enemy's strategy.

Invincibility lies in the defence; the possibility of victory in the attack.

When one treats people with benevolence, justice, and righteoousness, and reposes confidence in them, the army will be united in mind and all will be happy to serve their leaders'.

He will win who, prepared himself, waits to take the enemy unprepared.

Bravery without forethought, causes a man to fight blindly and desperately like a mad bull.  Such an opponent, must not be encountered with brute force, but may be lured into an ambush and slain.
