RV 10.42.3
किम् अङ्ग त्वा मघवन् भोजम् आहुः शिशीहि मा शिशयं त्वा शृणोमि । अप्नस्वती मम धीर् अस्तु शक्र वसुविदम् भगम् इन्द्रा भरा नः ॥
kim aṅga tvā maghavan bhojam āhuḥ śiśīhi mā śiśayaṃ tvā śṛṇomi | apnasvatī mama dhīr astu śakra vasuvidam bhagam indrā bharā naḥ ||
Devanagari rendered by HREEM from the edition's roman (IAST) text; the IAST is the edition's own.
Why, Maghavan, do they call thee Bounteous; Giver? Quicken me: thou, I hear, art he who quickens. Sakra, let my intelligence be active, and bring us luck that finds great wealth, O Indra.
Translated by Ralph T. H. Griffith (1896)
