akṣauhiṇyo hi bahulāstadbhārārtā vrajāmyadhaḥ /
tathā kurudhvaṃ tridaśā yathā śāntirbhavenmama //

“Perceiving the lord of the gods to have lost his uprightness and glory, to be powerless and formless, the Daityas endeavoured to conquer him. Daityas of exceeding might, desirous to conquer the lord of the gods, were born in the families of kings of surpassing valour, O great Muni. Then the Earth, afflicted with their weight, once went to the summit of Meru, where is the abode of the heaven-dwelling gods. Afflicted with their excessive weight, she declared that the cause of her distress arose from the Dānavas and Daityas. ‘These Asuras, widely resplendent, have been slain by you; they have all been born in the world of men in the families of kings; their armies are numerous indeed: oppressed by their weight, I am sinking downward; do ye, O ye thirty gods, devise how tranquillity may be attained for me.’
