RV 6.30.4
सत्यम् इत् तन् न त्वावां अन्यो अस्तीन्द्र देवो न मर्त्यो ज्यायान् । अहन्न् अहिम् परिशयानम् अर्णो ऽवासृजो अपो अच्छा समुद्रम् ॥
satyam it tan na tvāvāṃ anyo astīndra devo na martyo jyāyān | ahann ahim pariśayānam arṇo 'vāsṛjo apo acchā samudram ||
Devanagari rendered by HREEM from the edition's roman (IAST) text; the IAST is the edition's own.
This is the truth, none else is like thee, Indra, no God superior to thee, no mortal. Thou slewest Ahi who besieged the waters, and lettest loose the streams to hurry seaward.
Translated by Ralph T. H. Griffith (1896)
