yaste manyo'vidhadvajra sāyaka saha ojaḥ puṣyati viśvamānuṣak |
sāhyāma dāsamāryaṃ tvayā yujā sahatkṛtena sahasā sahasvatā ||

He who has served you, O Manyu, who are a thunderbolt and an arrow, fosters overpowering power and strength completely.\nMay we overcome the Dāsa and the Ārya with you as our ally, with overpowering might, vigorous and strong.
