RV 10.181.2
अविन्दन् ते अतिहितं यद् आसीद् यज्ञस्य धाम परमं गुहा यत् । धातुर् द्युतानात् सवितुश् च विष्णोर् भरद्वाजो बृहद् आ चक्रे अग्नेः ॥
avindan te atihitaṃ yad āsīd yajñasya dhāma paramaṃ guhā yat | dhātur dyutānāt savituś ca viṣṇor bharadvājo bṛhad ā cakre agneḥ ||
Devanagari rendered by HREEM from the edition's roman (IAST) text; the IAST is the edition's own.
These sages found what lay remote and hidden, the sacrifice's loftiest secret essence. From radiant Dhatar, Savitar, and Visnu, from Agni, Bharadvaja brought the Brhat.
Translated by Ralph T. H. Griffith (1896)
