RV 1.144.4
यम् ईं द्वा सवयसा सपर्यतः समाने योना मिथुना समोकसा । दिवा न नक्तम् पलितो युवाजनि पुरू चरन्न् अजरो मानुषा युगा ॥
yam īṃ dvā savayasā saparyataḥ samāne yonā mithunā samokasā | divā na naktam palito yuvājani purū carann ajaro mānuṣā yugā ||
Devanagari rendered by HREEM from the edition's roman (IAST) text; the IAST is the edition's own.
He whom the two copartners with observance tend, the pair who dwell together in the same abode, By night as in the day the grey one was born young, passing untouched by eld through many an age of man.
Translated by Ralph T. H. Griffith (1896)
