RV 1.164.47
कृष्णं नियानं हरयः सुपर्णा अपो वसाना दिवम् उत् पतन्ति । त आववृत्रन् सदनाद् ऋतस्याद् इद् घृतेन पृथिवी व्य् उद्यते ॥
kṛṣṇaṃ niyānaṃ harayaḥ suparṇā apo vasānā divam ut patanti | ta āvavṛtran sadanād ṛtasyād id ghṛtena pṛthivī vy udyate ||
Devanagari rendered by HREEM from the edition's roman (IAST) text; the IAST is the edition's own.
Dark the descent: the birds are golden-coloured; up to the heaven they fly robed in the waters. Again descend they from the seat of Order, and all the earth is moistened with their fatness.
Translated by Ralph T. H. Griffith (1896)
