Mahabharata Drona Parva Chapter 202:5

Mahabharata Drona Parva (Drona-vadha Parva) Chapter 202:5 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. And the triple-eyed Lord made Elapatra and Pushpadanta, the two pins of the yoke. And the valiant Mahadeva made the Malaya mountains the yoke, and the great Takshaka the string for tying the yoke to the poles, and the creatures about him the traces of the steed. And Maheswara made the four Vedas his four steeds. And that lord of the three worlds made the supplementary Vedas the bridle-bits. And Mahadeva made Gayatri and Savitri the reins, the syllable Om the whip, and Brahma the driver. And making the Mandara mountains the bow, Vasuki the bowstring, Vishnu his excellent shaft, Agni the arrow-head, and Vayu the two wings of that shafts, Yama the feathers in its tail, lightning the whetting stone, and Meru the standard, Siva, riding on that excellent car which was composed of all the celestial forces, proceeded for the destruction of the triple city. Indeed, Sthanu, that foremost of smiter, that Destroyer of Asuras, that handsome warrior of immeasurable prowess, adored by the celestials, O Partha, and by Rishis possessing wealth of asceticism, caused an excellent and unrivalled array called after his own name, and stood immovable for a thousand years. When, however, the three cities came together in the firmament, the lord Mahadeva pierced them with that terrible shaft of his, consisting of three knots. The Danavas were unable to gaze at that shafts inspired with Yuga-fire and composed of Vishnu and Soma. While the triple city commenced to burn, the goddess Parvati repaired thither to behold the sight. She had then on her lap, a child having a bald head with five clumps of hair on it.
