Lord Balarāma, who is also known as Saṅkarṣaṇa, began to fight with His club in such a heroic way that the river of blood created by Kṛṣṇa overflooded. Cowards became very much afraid upon seeing the ghastly and horrible scene, and heroes began to talk delightedly among themselves about the heroism of the two brothers. Although Jarāsandha was equipped with a vast ocean of military strength, the fighting of Lord Kṛṣṇa and Balarāma converted the whole situation into a ghastly scene far beyond ordinary fighting. Persons of ordinary merit cannot estimate how it could be possible, but when such activities are accepted as pastimes of the Supreme Personality of Godhead, under whose will everything is possible, then this can be understood. The Supreme Personality of Godhead creates, maintains and dissolves the cosmic manifestation merely by His will. For Him to create such a vast scene of devastation while fighting with an enemy is not so wonderful. And yet, because Kṛṣṇa and Balarāma were fighting with Jarāsandha just like ordinary human beings, the affair appeared wonderful.
When all the soldiers of Jarāsandha had been killed and he was the only one left alive, certainly he was very much depressed. Śrī Balarāma immediately arrested him with great strength, just as one lion captures another. But while Lord Balarāma was binding Jarāsandha with the rope of Varuṇa and ordinary ropes also, Lord Kṛṣṇa, with a greater plan in mind for the future, asked Lord Balarāma not to arrest him. Kṛṣṇa then released Jarāsandha. As a great fighting hero, Jarāsandha was ashamed, and he decided that he would no longer live as a king but would resign from his position in the royal order and go to the forest to practice meditation under severe austerities and penances.
As he was returning home with his royal friends, however, they advised him not to retire but to regain strength to fight again with Kṛṣṇa in the near future. The princely friends of Jarāsandha instructed him that ordinarily it would not have been possible for him to be defeated by the strength of the Yadu kings; the defeat he had experienced was simply due to his ill luck. The princely order encouraged King Jarāsandha. His fighting, they said, was certainly heroic; therefore, he should not take his defeat very seriously, since it was due only to his past misdeeds. After all, there was no fault in his fighting.
In this way, Jarāsandha, the King of Magadha Province, having lost all his strength and having been insulted by his arrest and subsequent release, could do nothing but return to his kingdom. Thus Lord Kṛṣṇa conquered the soldiers of Jarāsandha. Although Kṛṣṇa’s army was tiny in comparison to Jarāsandha’s, not a pinch of His strength was lost, whereas all of Jarāsandha’s men were killed.
The denizens of heaven were very much pleased, and they offered their respects by chanting in glorification of the Lord and showering Him with flowers, accepting the victory with great appreciation. Jarāsandha returned to his kingdom, and Mathurā City was saved from the danger of imminent attack. The citizens of Mathurā organized the combined services of professional singers like sūtas and māgadhas, along with poets who could compose nice songs, and they began to chant the victory glorification of Lord Kṛṣṇa. When Lord Kṛṣṇa entered the city after the victory, many bugles, conches and kettledrums sounded, and the vibrations of various musical instruments like bherīs, tūryas, vīṇās, flutes and mṛdaṅgas all joined together to make a beautiful reception. While Kṛṣṇa was entering, the whole city was cleansed, all the different streets and roads were sprinkled with water, and the inhabitants, being joyous, decorated their respective houses and shops with flags and festoons. The brāhmaṇas chanted Vedic mantras at numerous places. The people constructed road crossings and gates at entrances to lanes and streets. When Lord Kṛṣṇa was entering the nicely decorated city of Mathurā in a festive attitude, the ladies and girls of Mathurā prepared different kinds of flower garlands to make the ceremony most auspicious. In accordance with the Vedic custom, they took yogurt mixed with fresh green grass and strewed it here and there to make the victory jubilation even more auspicious. As Kṛṣṇa passed through the street, all the ladies and women regarded Him with eyes bright with great affection. Kṛṣṇa and Balarāma carried various kinds of ornaments, jewels and other booty carefully collected from the battlefield and presented it all to King Ugrasena. Kṛṣṇa thus offered His respect to His grandfather because Ugrasena was at that time the crowned king of the Yadu dynasty.
