"Have no hard feeling toward anyone who has not shown you enmity, do not fight with anyone who does not oppose you.  The effective skill of an engineer can only be seen by the eyes of an expert, the operation of plans in battle can only be set in action through the strategy of Sun Tzu."

 

"Planning should be secret, attack should be swift. When an army takes its objective like a hawk striking its prey, and battles like a river broken through a dam, its opponents will scatter before the army tires. This is the use of the momentum of an army."

 

"A skilled attack is one against which opponents do not know how to defend; a skilled defense in one which opponents do not know how to attack.  Therefore those killed in defense are not so because of fortress walls.  This is why high walls and deep moats do not guarantee security, while strong armor and effective weapons do not guarantee strength.  If opponents want to hold firm, attack where they are unprepared; if opponents want to establish a battlefront, appear where they do not expect you."

 

 

"I have three treasures that I keep and prize: one is kindness, second is frugality, and third is not presuming to take precedence over ours.  By kindness one can be bra, by frugality one can reach out, and by not presuming to take precedence one can survive effectively. If one gives upon frugality and breadth, and gives up humility for aggressiveness, one will die.  The exercise of kindness and courage, without which one will die. The exercise of kindness in battle leads to victory, the exercise of kindness in defense leads to security.
