RV 1.164.10
तिस्रो मातॄस् त्रीन् पितॄन् बिभ्रद् एक ऊर्ध्वस् तस्थौ नेम् अव ग्लापयन्ति । मन्त्रयन्ते दिवो अमुष्य पृष्ठे विश्वविदं वाचम् अविश्वमिन्वाम् ॥
tisro mātṝs trīn pitṝn bibhrad eka ūrdhvas tasthau nem ava glāpayanti | mantrayante divo amuṣya pṛṣṭhe viśvavidaṃ vācam aviśvaminvām ||
Devanagari rendered by HREEM from the edition's roman (IAST) text; the IAST is the edition's own.
Bearing three Mothers and three Fathers, single he stood erect: they never make him weary. There on the pitch of heaven they speak together in speech all-knowing but not all-impelling.
Translated by Ralph T. H. Griffith (1896)
