dorbhyām utkṛtta-mūlābhyāṁ
babhau rakta-sravo 'suraḥ
chinna-pakṣo yathā gotraḥ
khād bhraṣṭo vajriṇā hataḥ
dorbhyām - from the two arms; utkṛtta-mūlābhyām - cut from the very root; babhau - was; rakta-sravaḥ - profusely discharging blood; asuraḥ - Vṛtrāsura; chinna-pakṣaḥ - whose wings are cut; yathā - just as; gotraḥ - a mountain; khāt - from the sky; bhraṣṭaḥ - falling; vajriṇā - by Indra, the carrier of the thunderbolt; hataḥ - struck.
It appears from the statement of this verse that sometimes there are flying mountains and that their wings are cut by the thunderbolt of Indra. Vṛtrāsura’s huge body resembled such a mountain.
