इन्द्रो मह्ना महतो अर्णवस्य वि मूर्धानम् अभिनद् अर्बुदस्य । अहन्न् अहिम् अरिणात् सप्त सिन्धून् देवैर् द्यावापृथिवी प्रावतं नः ॥
indro mahnā mahato arṇavasya vi mūrdhānam abhinad arbudasya | ahann ahim ariṇāt sapta sindhūn devair dyāvāpṛthivī prāvataṃ naḥ ||
Devanagari rendered by HREEM from the edition's roman (IAST) text; the IAST is the edition's own.
Indra with mighty strength cleft asunder the head of Arbuda the watery monster, Slain Ahi, and set free the Seven Rivers. O Heaven and Earth, with all the Gods protect us.
Translated by Ralph T. H. Griffith (1896)
