Diminishing War

"He who in the use of Tau renders assistance to a human ruler, does not use weapons to force the people. His actions are such as he may well accept the results of (or, such as he would wish rendered to himself again). Where legions are quartered, briars and thorns grow. In the track of great armies, there must follow bad years. The good soldier is brave in need only (to effect some good purpose). He ventures nothing for the sake of power. He is brave in need, but not a bully. He is brave in need, but not a boaster. He is brave in need, but is not over-bearing. He is brave in need, but he cannot be less. He is brave in need, but not violent. When things reach their highest pitch of vigour, they become old. This is called not Tau. What is not Tau is soon at an end."
