Chapter Fifty contains fifty-seven verses. In this chapter, Jarāsandha, having heard that his son-in-law Kaṁsa was killed, attacked Mathurā to kill Rāma and Kṛṣṇa but was defeated seventeen times. When Jarāsandha was about to attack for the eighteenth time, Kālayavana, having been advised by Nārada, also attacked Mathurā. Thus the Yādava dynasty entered a fort in the midst of the water and lived there by mystic power. After giving full protection to the Yādava dynasty and conferring with Lord Baladeva, Lord Kṛṣṇa emerged from Dvārakā. Chapter Fifty-one, which contains sixty-three verses, describes how Mucukunda killed Kālayavana simply by glancing upon him.
