Devanagari rendered by HREEM from the edition's roman (IAST) text; the IAST is the edition's own.
Man's worship of the Gods hath three great lustres, and three celestial lights have they established The Maruts gifted with pure strength adore thee, for thou, O Indra, art their sapient Rsi.
Translated by Ralph T. H. Griffith (1896)
