RV 7.49.1
समुद्रज्येष्ठाः सलिलस्य मध्यात् पुनाना यन्त्य् अनिविशमानाः । इन्द्रो या वज्री वृषभो रराद ता आपो देवीर् इह माम् अवन्तु ॥
samudrajyeṣṭhāḥ salilasya madhyāt punānā yanty aniviśamānāḥ | indro yā vajrī vṛṣabho rarāda tā āpo devīr iha mām avantu ||
Devanagari rendered by HREEM from the edition's roman (IAST) text; the IAST is the edition's own.
Forth from the middle of the flood the Waters-their chief the Sea-flow cleansing, never sleeping. Indra, the Bull, the Thunderer, dug their channels: here let those Waters, Goddesses, protect me.
Translated by Ralph T. H. Griffith (1896)
