[paragraph continues] The minds of men, O king, become weak and confounded like those of persons wounded with weapons, when sinfulness is not restrained. Casting their eyes on both the worlds, the Rishis made the king, that superior being, intending that he should be the embodiment of righteousness on earth. He is called Rajan in whom righteousness shines. That king, again in whom there is no righteousness, is called a Vrishala. The divine Dharma (righteousness) has another name, viz., Vrisha. He who weakens Vrisha is called by the name of Vrishala. A king should, therefore, advance the cause of righteousness. All creatures grow in the growth of righteousness, and decay with its decay. Righteousness, therefore, should never be permitted to decay. Righteousness is called Dharma because it aids the acquisition and preservation of wealth (Dhana). The sages, O king, have declared that Dharma restrains and set bounds to all evil acts of men. The self-born (Brahman) created Dharma for the advancement and growth of creatures. For this reason, a king should act according to the dictates of Dharma for benefiting his subjects. For this reason also, O tiger among kings, Dharma has been said to be the foremost of all things. That foremost of men who rules his subjects righteously is called a king. Disregarding lust and wrath, observe thou the dictates of righteousness. Among all things, O chief of Bharata's race, that conduce to the prosperity of kings, righteousness is the foremost.
