When one treats people with benevolence, justice and righteousness, and reposes confidence in them, the army will be united in mind and all will be happy to serve their leaders.

Attack where he is unprepared; sally forth when he does not expect you.

He who relies solely on warlike measures shall be exterminated; he who relies solely on peaceful measures shall perish.
