RV 10.30.1
प्र देवत्रा ब्रह्मणे गातुर् एत्व् अपो अच्छा मनसो न प्रयुक्ति । महीम् मित्रस्य वरुणस्य धासिम् पृथुज्रयसे रीरधा सुवृक्तिम् ॥
pra devatrā brahmaṇe gātur etv apo acchā manaso na prayukti | mahīm mitrasya varuṇasya dhāsim pṛthujrayase rīradhā suvṛktim ||
Devanagari rendered by HREEM from the edition's roman (IAST) text; the IAST is the edition's own.
As 'twere with swift exertion of the spirit, let the priest speed to the celestial Waters, The glorious food of Varuna and Mitra. To him who spreadeth far this laud I offer.
Translated by Ralph T. H. Griffith (1896)
