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. The goddess asked the deities as to who that child was. Sakra, through ill-feeling endeavoured to strike that child with his thunderbolt. The divine lord Mahadeva (for the child was none other), smiling, quickly paralysed the arm of the enraged Sakra. Then god Sakra, with his arm paralysed accompanied by all the celestials, speedily repaired to the lord Brahma of unfading glory.
