Royal authority is a noble and enjoyable position. It comprises all the good things of the world, the pleasures of the body, and the joys of the soul. Therefore, there is, as a rule, great competition for it. It rarely is handed over (voluntarily), but it may be taken away. Thus, discord ensues. It leads to war and fighting, and to attempts to gain superiority.
