Mbh 12.59.3l

That high-souled king caused all creatures to regard righteousness as the foremost of all things; and because he gratified all the people, therefore, was he called Rajan (king). And because he also healed the wounds of Brahmanas, therefore, he earned the name of Kshatriya. And because the earth (in his region) became celebrated for the practice of virtue, therefore, she came to be called by many as Prithvi. The eternal Vishnu himself, O Bharata, confirmed his power, telling him, 'No one, O king, shall transcend thee.' The divine Vishnu entered the body of that monarch in consequence of his penances. For this reason, the entire universe offered divine worship unto Prithu, numbered among human gods.[175] O king, thy kingdom should always be protected by the aid of the science of chastisement. Thou shouldst also, by careful observation made through the movements of thy spies, protect it in such a way that no one may be able to injure it.[176] All good acts, O king, lead to the good (of the monarch). The conduct of a king should be regulated by his own intelligence, as also by the opportunities and means that may offer themselves.[177] What other cause is there in consequence of which the multitude live in obedience to one, save the divinity of the monarch? At that time a golden lotus was born from Vishnu's brow. The goddess Sree was born of that lotus. She became the spouse of Dharma of great intelligence; upon Sree, O son of Pandu, Dharma begot Artha. All the three, viz., Dharma, and Artha and Sree, were established in sovereignty. A person upon the exhaustion of his merit, comes down from heaven to earth, and takes birth as a king conversant with the science of chastisement. Such a person becomes endued with greatness and is really a portion of Vishnu on earth. He becomes possessed of great intelligence and obtains superiority over others. Established by the gods, no one transcends him.
