Bhagavatapurana 10.66.39

39. Brilliant like a million Suryas (suns) and flaming forth like the fire of deluge and pervading all the directions, heaven and earth, with his lustre and force, Chakra, the weapon of Mnkunda,, beat down that Maheswara fire.

40. O king! thus beaten by the force of Sri Krishna's weapon the magic fire had its force blunted: and returning abashed to Benares and being started by them, it burnt up Sudakshina and his priests. 41. Following it Vishnu's Chakra entered the city of Varanasi, traversed its upper stories, balconeys, halls, mansions, markets, towers, enclosures with which the city was overfull, through the treasuries, stalls, arches and yards of elephants horses and chariots, kitchens and dining halls.
