RV 10.149.2
यत्रा समुद्र स्कभितो व्य् औनद् अपां नपात् सविता तस्य वेद । अतो भूर् अत आ उत्थितं रजो ऽतो द्यावापृथिवी अप्रथेताम् ॥
yatrā samudra skabhito vy aunad apāṃ napāt savitā tasya veda | ato bhūr ata ā utthitaṃ rajo 'to dyāvāpṛthivī aprathetām ||
Devanagari rendered by HREEM from the edition's roman (IAST) text; the IAST is the edition's own.
Well knoweth Savitar, O Child of Waters, where ocean, firmly fixt, o'erflowed its limit. Thence sprang the world, from that uprose the region: thence heaven spread out and the wide earth expanded.
Translated by Ralph T. H. Griffith (1896)
