Mbh 7.202.3f

Smilingly Sankara approached him and tore out his teeth. The gods then, humbling themselves to him, fled away, trembling. Once more, Mahadeva aimed at the gods a shower of blazing and keen arrows resembling flames of fire mixed with smoke, or clouds with lightning. Beholding that arrowy shower, all the gods bowing down unto Maheswara, assigned to Rudra a substantial share in sacrifices. In fright, the gods, O prince, sought his protection. His wrath being dispelled, the great God then restored the sacrifice. The gods that had fled away came back. Indeed, they are to this day afraid of Maheswara. Formerly, the valiant Asuras had, in heaven, three cities. Each of those cities was excellent and large. One was made of iron, another of silver, and the third of gold. The golden city belonged to Kamalaksha, the silver city to Tarakaksha, and the third, made of iron, had Vidyunmalin for its lord. With all his weapons, Maghavat (Indra) was unable to make any impression on those cities. Afflicted (by the Asuras), all the gods sought the protection of Rudra. Approaching him, all the gods with Vasava at their head, said, ‘These terrible dwellers of the triple city have received boons from Brahma. Filled with pride in consequence of those boons, they are greatly afflicting the universe, O Lord of the gods, none, save thee, is competent to slay them. Therefore, O Mahadeva, slay these enemies of the gods: O Rudra, creatures slain in every sacrifice shall then be thine.’ Thus addressed by the gods, Mahadeva thus accepted their request, moved by the desire of benefiting them, and said, ‘I will overthrow these Asuras.’ And Hara made the two mountains, viz., Gandhamadana and Vindhya, the two poles of his car. And Sankara made the earth with her oceans and forests his battle car. And the three-eyed deity made that prince of snakes, viz., Sesha, the Aksha, of that car. And that God of gods, the wielder of Pinaka, made the moon and the sun the two wheels of that vehicle.
