ā́ krandaya bálam ójo na ā́ dhā abhí ṣṭana duritā́ bā́dhamānaḥ |
ápa sedha dundubhe duchúnām itá índrasya muṣṭír asi vīḍáyasva ||2||

Resound thou at [them]; mayest thou assign strength [and] force to us; thunder against [them], forcing off difficulties; drive, O drum, misfortune away from here; Indra's fist art thou; be stout.
