Lord Kṛṣṇa continued: "There is no one in the three worlds of the universe, including the powerful demigods, who can surpass My devotees in any of the six opulences, namely wealth, strength, reputation, beauty, knowledge and renunciation. Therefore, if you want to conquer the worldly kings, there is no possibility of their emerging victorious."
When Lord Kṛṣṇa thus encouraged King Yudhiṣṭhira, the King's face brightened like a blossoming flower because of transcendental happiness, and thus he ordered his younger brothers to conquer all the worldly kings in all directions. Lord Kṛṣṇa empowered the Pāṇḍavas to execute His great mission of chastising the infidel miscreants of the world and giving protection to His faithful devotees. In His Viṣṇu form, the Lord carries four weapons in His four hands—a lotus flower and a conchshell in two hands, and in the other two hands a club and a disc. The club and disc are meant for the infidel miscreants and demons, and the lotus flower and conchshell are for the devotees. But because the Lord is the Supreme Absolute, the result of all His weapons is one and the same. With the club and the disc He chastises the miscreants so that they may come to their senses and know that they are not all in all, for above them there is the Supreme Lord. And by bugling with the conchshell and offering blessings with the lotus flower, He always assures the devotees that no one can vanquish them, even in the greatest calamity. King Yudhiṣṭhira, being thus assured by the indication of Lord Kṛṣṇa, ordered his youngest brother, Sahadeva, accompanied by soldiers of the Sṛñjaya tribe, to conquer the southern countries. Similarly, he ordered Nakula, accompanied by the soldiers of Matsyadeśa, to conquer the kings of the western side. He sent Arjuna, accompanied by the soldiers of Kekayadeśa, to conquer the kings of the northern side, and he ordered Bhīmasena, accompanied by the soldiers of Madradeśa (Madras), to conquer the kings on the eastern side.
It may be noted that by dispatching his younger brothers to conquer in different directions, King Yudhiṣṭhira did not actually intend that they declare war upon the kings. Actually, the brothers started for different directions to inform the respective kings about King Yudhiṣṭhira's intention to perform the Rājasūya sacrifice. The kings were thus informed that they were required to pay taxes for the execution of the sacrifice. This payment of taxes to Emperor Yudhiṣṭhira meant that the king accepted subjugation before him. In case of a king's refusal to act accordingly, there was certainly a fight. Thus by their influence and strength the brothers conquered all the kings in different directions, and they were able to bring in sufficient taxes and presentations, which they brought before King Yudhiṣṭhira.
