Concentration of mind, exertion and destiny, (these three) exist as the three causes of victory. One who possesses velour, but does act with carelessness can never win victory; It is for this that a many endued with strength sometimes suffers death at the hands of his enemies. As meanness overtakes the weak, so folly sometimes overtakes the strong. A king therefore, who is desirous of victory, should forsake both these causes of destruction.
