RV 4.6.4
स्तीर्णे बर्हिषि समिधाने अग्ना ऊर्ध्वो अध्वर्युर् जुजुषाणो अस्थात् । पर्य् अग्निः पशुपा न होता त्रिविष्ट्य् एति प्रदिव उराणः ॥
stīrṇe barhiṣi samidhāne agnā ūrdhvo adhvaryur jujuṣāṇo asthāt | pary agniḥ paśupā na hotā triviṣṭy eti pradiva urāṇaḥ ||
Devanagari rendered by HREEM from the edition's roman (IAST) text; the IAST is the edition's own.
When sacred grass is strewn and Agni kindled, the Adhvaryu rises to, his task rejoicing. Agni the Priest, like one who tends the cattle, goes three times round, as from of old he wills it.
Translated by Ralph T. H. Griffith (1896)
