“A warrior of light respects the main teaching of the I Ching: 'To persevere is favourable.'He knows that perseverance is not the same thing as insistence. There aretimes when battles go on longer than necessary, draining him of strength andenthusiasm.At such moments, the warrior thinks: 'A prolonged war finally destroys thevictors too.'Then he withdraws his forces from the battlefield and allows himself arespite. He perseveres in his desire, but knows he must wait for the best moment to attack.A warrior always returns to the fray. He never does so out of stubbornness,but because he has noticed a change in the weather.”
