SB 1.10 - Yudhiṣṭhira, the king representing Kṛṣṇa
Śaunaka asked how Mahārāja Yudhiṣṭhira ruled his subjects after killing his enemies in battle. Yudhiṣṭhira was not at all inclined to fight with his cousins but he fought nevertheless for a right cause under the guidance of Lord Kṛṣṇa. But he could not freely enjoy his kingdom with unrestricted consciousness. The enemies desired his wealth and obtained it. But he took it back from them. Sūta replied that Kṛṣṇa, upon whom Śiva meditates, became pleased by protecting Parīkṣit and after reestablishing Yudhiṣṭhira in his own kingdom. Just as a forest fire occurs automatically by the cohesion of bamboos, in the material world the fire of war takes place by the wrath of those who want to lord it over material nature. The Lord has nothing to do with such wars but the Lord wants the suffering souls to come back to Him. The whole plan of creation is made in that way, and the illusory energy punishes the rebellious souls. Kṛṣṇa established the righteous rule of the Pāṇḍavas and was fully satisfied to see Yudhiṣṭhira on the throne, and the seedling of the dynasty of Kuru, Mahārāja Parīkṣit saved. And Yudhiṣṭhira took up the ruling of the country only after seeing that Kṛṣṇa was pleased.
Yudhiṣṭhira, after being enlightened by Bhīṣma and Lord Kṛṣṇa, engaged himself in matters of perfect knowledge. Thus he ruled the earth and seas with the cooperation of his younger brothers, who acted as his ministers and commanders of state. This was just like Indra, having taken shelter of Upendra, rules over heaven extending in all directions with the compliance of Upendra. Yudhiṣṭhira was the ideal king or representative of Lord Kṛṣṇa to rule over the earth and was comparable to Indra, the ruler of the heavenly planets. The demigods like Indra, Candra, Sūrya, Varuṇa and Vāyu are representative kings of different planets of the universe and similarly Yudhiṣṭhira was one of them ruling over the earth. Even if the modern elected executive head of a state is enlightened like Yudhiṣṭhira, he cannot do anything out of his own good will due to his constitutional position. Therefore, there are so many states quarreling because of ideological differences or other selfish motives. But a king like Yudhiṣṭhira had no ideology of his own, but simply followed the instructions of the Lord and His representative, Bhīṣma. Therefore, it was possible for him to rule the whole world because the principles were infallible and universally applicable to everyone.
