Act after having made assessments. The one who first knows the measure of far and near wins - this is the rule of armed struggle.

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

Attack like the Fire and be still as the Mountain

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

The military has no constant form, just as water has no constant shape - adapt as you face the enemy, without letting them know beforehand what you are going to do.

If this is long delayed, weapons are blunted and morale depressed.

All war is deception.
