If the mind is willing, the flesh could go on and on without many things.

the leader of armies is the arbiter of the people's fate, the man on whom it depends whether the nation shall be in peace or in peril.

The best general is the one who never fights.

Thus the highest form of generalship is to balk the enemy's plans, the next best is to prevent the junction of the enemy's forces, the next in order is to attack the enemy's army in the field, and the worst policy of all is to besiege walled cities.

The peak efficiency of knowledge and strategy is to make conflict unnecessary.

Secret operations are essential in war; upon them the army relies to make its every move.

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