Rig Veda
उ॒ग्रं यु॑युज्म॒ पृत॑नासु सास॒हिमृ॒णका॑ति॒मदा॑भ्यम् । वेदा॑ भृ॒मं चि॒त्सनि॑ता र॒थीत॑मो वा॒जिनं॒ यमिदू॒ नश॑त् ॥ उग्रं युयुज्म पृतनासु सासहिमृणकातिमदाभ्यम् । वेदा भृमं चित्सनिता रथीतमो वाजिनं यमिदू नशत् ॥
We join (to our rite) the mighty Indra, the subduer of enemies in battles, the inviolate, him to whompraise is due as a debt; he, the best of charioteers, knows (among steeds) the strong racer, and (among men)he, the bounteous (knows) the offerer whom he is to reach.
