RV 7.7.1
प्र वो देवं चित् सहसानम् अग्निम् अश्वं न वाजिनं हिषे नमोभिः । भवा नो दूतो अध्वरस्य विद्वान् त्मना देवेषु विविदे मितद्रुः ॥
pra vo devaṃ cit sahasānam agnim aśvaṃ na vājinaṃ hiṣe namobhiḥ | bhavā no dūto adhvarasya vidvān tmanā deveṣu vivide mitadruḥ ||
Devanagari rendered by HREEM from the edition's roman (IAST) text; the IAST is the edition's own.
I SEND forth even your God, victorious Agni, like a strong courser, with mine adoration. Herald of sacrifice be he who knoweth he hath reached Gods, himself, with measured motion.
Translated by Ralph T. H. Griffith (1896)
