Thereupon, enraged, Krishna took up a handful of rushes to destroy them, which became a club of iron; and with this he killed many of the murderous Yādavas, whilst others fighting fiercely destroyed one another. At this time in the very presence of Krishna's charioteer, his swift steeds carried off his Jaitra car and entered into the sea. The discus, the club, the bow, the quiver, the shell and the sword of Kesava, having circumambulated their master, flew along the path of the sun. In a short time there was not a single Yādava left alive save the mighty Krishna and Dāruka. Going towards Rāma, who was sitting at the root of a tree, they saw a huge serpent coming out of his mouth. Having issued out of his mouth, the mighty snake proceeded towards the ocean hymned by saints and other great snakes. Bringing an offering of respect, the ocean came to him and then the majestic being worshipped of all the attendant snakes, entered into the waters of the deep. Beholding the departure of the spirit of Baladeva, Kesava said to Dāruka—"Do thou go to Vasudeva and Ugrasena and communicate unto him this. Go and inform them of the departure of Balabhadra, and the destruction of the Yādava race, and also that I shall engage in religious meditation and renounce my body. Do thou also inform Ahuka and the inhabitants of Dwārakā that their city shall be inundated by the ocean. And do ye await the arrival of Arjuna at Dwārakā. When Arjuna, the descendant of Pāndu, shall issue out of the city, none of you should wait there but go whither the descendant of Kuru shall repair. Do thou also go to the son of Kunti and tell him that he may at my request protect my family according to his might. Then go to Hastināpur with Arjuna and all the inhabitants of Dwārakā and let Vajra be installed king over the race of Yadu".
