Vishnupurana 5.34.p7

5.34.p7

The arms of the king of Kāsi and the whole number of the attendant divinities of Siva armed with various weapons marched out to oppose the discus. But an expert in the use of arms he consumed the whole host by his radiance and then set fire to the city, in which the magic power of Siva had concealed herself. Thus was Varanashi burnt with all its princes and their followers, its inhabitants, elephants, horses and men, treasures and granaries, houses, palaces and markets. The whole of the city that was inaccessible to the celestials was thus covered with flames by the discus of Hari and was totally destroyed. The discus, with unsoothed wrath, blazing fiercely and not satisfied with the accomplishment of so easy a task, then returned to the hands of Vishnu.
