Ramayana 2.74.35

इति नाग इवारण्ये तोमराङ्कुशचोदितः।पपात भुवि सङ्कृद्धो निश्श्वसन्निव पन्नगः।।।।

iti nāga ivāraṇye tomarāṅkuśa-coditaḥ | papāta bhuvi saṅkruddho niśśvasann iva pannagaḥ ||

Having spoken thus, Bharata—like an elephant in the forest driven by spears and goads—fell upon the earth in wrath, hissing like a serpent.
