After Kaṁsa was killed, his two queens, Asti and Prāpti, went to the home of their father, Jarāsandha, and sorrowfully described to him how Kṛṣṇa had made them widows. Upon hearing this account, King Jarāsandha became angry. He vowed to rid the earth of all the Yādavas, and he gathered an immense army to lay siege to Mathurā. When Śrī Kṛṣṇa saw Jarāsandha attacking, the Lord considered the reasons for His descent to this world and then decided to destroy Jarāsandha’s army, which was a burden to the earth.
