War is a matter of vital importance to the state.

There are routes not to be followed, armies not to be attacked, citadels not to be besieged, territory not to be fought over.

Of all those in the army close to the commander, none is more intimate than the secret agent.

Against those skilled in attack, an enemy does not know where to defend; against the experts in defense, the enemy does not know where to attack.

Until death itself comes, no calamity need be feared

All warfare is based on deception. Therefore, when capable, feign incapacity; when active, inactivity. When near, make it appear that you are far away; when far away, that you are to lure him; feign disorder and strike him. When he concentrates, prepare against him; where he is strong, avoid him. Anger his general and confuse him. Pretend inferiority and encourage his arrogance.

Peace proposals unaccompanied by a sworn covenant indicate a plot.
