"The general who is skilled in defense hides in the most secret recesses of the earth; he who is skilled in attack flashes forth from the topmost heights of heaven."

"If I am able to determine the enemy's dispositions while at the same time I conceal my own, then I can concentrate and he must divide."

"If the enemy is in superior strength, evade him."

"Move not unless you see an advantage; use not your troops unless there is something to be gained; fight not unless the position is critical."

"Appear at points which the enemy must hasten to defend; march swiftly to places where you are not expected."
