RV 5.63.2
सम्राजाव् अस्य भुवनस्य राजथो मित्रावरुणा विदथे स्वर्दृशा । वृष्टिं वां राधो अमृतत्वम् ईमहे द्यावापृथिवी वि चरन्ति तन्यवः ॥
samrājāv asya bhuvanasya rājatho mitrāvaruṇā vidathe svardṛśā | vṛṣṭiṃ vāṃ rādho amṛtatvam īmahe dyāvāpṛthivī vi caranti tanyavaḥ ||
Devanagari rendered by HREEM from the edition's roman (IAST) text; the IAST is the edition's own.
This world's imperial Kings, O Mitra-Varuna, ye rule in holy synod, looking on the light. We pray for rain, your boon, and immortality. Through heaven and over earth the thunderers take their way.
Translated by Ralph T. H. Griffith (1896)
