RV 10.23.3
यदा वज्रं हिरण्यम् इद् अथा रथं हरी यम् अस्य वहतो वि सूरिभिः । आ तिष्ठति मघवा सनश्रुत इन्द्रो वाजस्य दीर्घश्रवसस् पतिः ॥
yadā vajraṃ hiraṇyam id athā rathaṃ harī yam asya vahato vi sūribhiḥ | ā tiṣṭhati maghavā sanaśruta indro vājasya dīrghaśravasas patiḥ ||
Devanagari rendered by HREEM from the edition's roman (IAST) text; the IAST is the edition's own.
When, with the Princes, Maghavari, famed of old, comes nigh the thunderbolt of gold, and the Controller's car Which his two Tawny Coursers draw, then Indra is the Sovran Lord of power whose glory spreads afar.
Translated by Ralph T. H. Griffith (1896)
