Devanagari rendered by HREEM from the edition's roman (IAST) text; the IAST is the edition's own.
Agni, thou beamest forth with light, great Hero, never changed by time. Shining, pure Agni! with a light that never fades, beam with thy fair beams brilliantly.
Translated by Ralph T. H. Griffith (1896)
