RV 10.21.1
आग्निं न स्ववृक्तिभिर् होतारं त्वा वृणीमहे । यज्ञाय स्तीर्णबर्हिषे वि वो मदे शीरम् पावकशोचिषं विवक्षसे ॥
āgniṃ na svavṛktibhir hotāraṃ tvā vṛṇīmahe | yajñāya stīrṇabarhiṣe vi vo made śīram pāvakaśociṣaṃ vivakṣase ||
Devanagari rendered by HREEM from the edition's roman (IAST) text; the IAST is the edition's own.
With offerings of our own we choose thee, Agni, as Invoking Priest, For sacrifice with trimmed grass,-at your glad carouse-piercing and brightly shining. Thou art waxing great.
Translated by Ralph T. H. Griffith (1896)
