In plain words
You too, do not try to understand His magic. It will be better if you keep out of His way and hold your tongue,” she advised him. “Where did this servant woman get such boldness?” Kaṃsa wondered. He thought that Kṛṣṇa Himself might have urged her to speak to him like this. Just then someone came, and Kaṃsa's attention turned that way. Meanwhile Kubjā quietly slipped away from there.
Kaṃsa sent his men, telling them to kill Kṛṣṇa and Balarāma. Unable to withstand Kṛṣṇa's onslaught, they fell at His feet. Then Kṛṣṇa and Balarāma entered Kaṃsa's court like lion cubs. A wrestling match was going on there. Kaṃsa sat on the dais watching the contest. Kṛṣṇa and Balarāma flew up like birds and leapt down upon Kaṃsa. They seized him by the neck, dragged him down, rained blows on him with their fists and beat him to a pulp. Kṛṣṇa set His foot on his belly and tore him open. Seeing this sight, the members of the court stood stunned. They marvelled how Kṛṣṇa, a little boy, had been able to kill the mighty Kaṃsa.
Back in Vrepalle, all the people were waiting for Kṛṣṇa and Balarāma to come. The Gopīs were weeping, afraid that Kaṃsa might have planned some harm to them; they were cursing Kaṃsa with whatever came to their lips. Yaśodā and Nanda too were anxious. All the Gopīs went on keeping Kṛṣṇa's name in mind, saying ‘Kṛṣṇa, Kṛṣṇa’. Later, hearing the news of Kaṃsa's death, they celebrated a festival in their joy.
After Kaṃsa died, both his wives went back to their parents' home. They were the daughters of Jarāsandha. Jarāsandha was angry that Kṛṣṇa had killed Kaṃsa and wronged his daughters. He and his kinsmen bore hatred towards Kṛṣṇa. Hearing of this, Yaśodā and Nanda grew anxious. But Devakī Devī was a woman of great courage and a supreme devotee. She stayed courageous, sure that no one could harm Kṛṣṇa.
