RV 2.30.2
यो वृत्राय सिनम् अत्राभरिष्यत् प्र तं जनित्री विदुष उवाच । पथो रदन्तीर् अनु जोषम् अस्मै दिवे-दिवे धुनयो यन्त्य् अर्थम् ॥
yo vṛtrāya sinam atrābhariṣyat pra taṃ janitrī viduṣa uvāca | patho radantīr anu joṣam asmai dive-dive dhunayo yanty artham ||
Devanagari rendered by HREEM from the edition's roman (IAST) text; the IAST is the edition's own.
His Mother-for she knew-spake and proclaimed him who was about to cast his bolt at Vrtra. Cutting their paths according to his pleasure day after day flow to their goal the rivers.
Translated by Ralph T. H. Griffith (1896)
