RV 3.55.12
माता च यत्र दुहिता च धेनू सबर्दुघे धापयेते समीची । ऋतस्य ते सदसीळे अन्तर् महद् देवानाम् असुरत्वम् एकम् ॥
mātā ca yatra duhitā ca dhenū sabardughe dhāpayete samīcī | ṛtasya te sadasīḷe antar mahad devānām asuratvam ekam ||
Devanagari rendered by HREEM from the edition's roman (IAST) text; the IAST is the edition's own.
Where the two Cows, the Mother and the Daughter, meet and give suck yielding their lordly nectar, I praise them at the seat of law eternal. Great is the Gods' supreme and sole dominion.
Translated by Ralph T. H. Griffith (1896)
