RV 10.31.7
किं स्विद् वनं क उ स वृक्ष आस यतो द्यावापृथिवी निष्टतक्षुः । संतस्थाने अजरे इतऊती अहानि पूर्वीर् उषसो जरन्त ॥
kiṃ svid vanaṃ ka u sa vṛkṣa āsa yato dyāvāpṛthivī niṣṭatakṣuḥ | saṃtasthāne ajare itaūtī ahāni pūrvīr uṣaso jaranta ||
Devanagari rendered by HREEM from the edition's roman (IAST) text; the IAST is the edition's own.
What was the tree, what wood, in sooth, produced it, from which they fashioned forth the Earth and Heaven? These Twain stand fast and wax not old for ever: these have sung praise to many a day and morning.
Translated by Ralph T. H. Griffith (1896)
