RV 10.23.1
यजामह इन्द्रं वज्रदक्षिणं हरीणां रथ्यं विव्रतानाम् । प्र श्मश्रु दोधुवद् ऊर्ध्वथा भूद् वि सेनाभिर् दयमानो वि राधसा ॥
yajāmaha indraṃ vajradakṣiṇaṃ harīṇāṃ rathyaṃ vivratānām | pra śmaśru dodhuvad ūrdhvathā bhūd vi senābhir dayamāno vi rādhasā ||
Devanagari rendered by HREEM from the edition's roman (IAST) text; the IAST is the edition's own.
Indra, whose right hand wields the bolt, we worship, driver of Bay Steeds seeking sundered courses. Shaking his beard with might he hath arisen, casting his weapons forth and dealing bounties.
Translated by Ralph T. H. Griffith (1896)
