RV 10.191.3
समानो मन्त्रः समितिः समानी समानम् मनः सह चित्तम् एषाम् । समानम् मन्त्रम् अभि मन्त्रये वः समानेन वो हविषा जुहोमि ॥
samāno mantraḥ samitiḥ samānī samānam manaḥ saha cittam eṣām | samānam mantram abhi mantraye vaḥ samānena vo haviṣā juhomi ||
Devanagari rendered by HREEM from the edition's roman (IAST) text; the IAST is the edition's own.
The place is common, common the assembly, common the mind, so be their thought united. A common purpose do I lay before you, and worship with your general oblation.
Translated by Ralph T. H. Griffith (1896)
