When the inhabitants of Káśí saw the head of their king shot into their city, they were much astonished, and wondered how it could have happened, and by whom the deed could have been done. Having ascertained that the king had been killed by Krishńa, the son of the monarch of Káśí, together with the priest of the family, propitiated Śankara; and that deity, well pleased to be adored in the sacred place Avimukta, desired the prince to demand a boon: on which he prayed, and said, "O lord, mighty god, through thy favour let thy mystic spirit arise to destroy Krishńa, the murderer of my father." "It shall be so," answered Śankara: and from out of the southern fire upsprang a vast and formidable female, like flame out of fire, blazing with ruddy light, and with fiery radiance streaming amidst her hair. Angrily she called upon Krishńa, and departed to Dwáraká; where the people, beholding her, were struck with dismay, and fled for protection to Madhusúdana, the refuge of all worlds. The wielder of the discus knowing that the fiend had been produced by the son of the king of Káśí, through his adoration of the deity whose emblem is a bull, and being engaged in sportive amusements, and playing at dice, said to the discus, "Kill this fierce creature, whose tresses are of plaited flame." Accordingly Sudarśana, the discus of Vishńu, immediately attacked the fiend, fearfully enwreathed with fire, and wearing tresses of plaited flame. Terrified at the might of Sudarśana, the creation of Maheśwara awaited not his attack, but fled with speed, pursued by him with equal velocity, until she reached Varánáśí, repelled by the superior might of the discus of Vishńu.
