RV 1.166.4
आ ये रजांसि तविषीभिर् अव्यत प्र व एवासः स्वयतासो अध्रजन् । भयन्ते विश्वा भुवनानि हर्म्या चित्रो वो यामः प्रयतास्व् ऋष्टिषु ॥
ā ye rajāṃsi taviṣībhir avyata pra va evāsaḥ svayatāso adhrajan | bhayante viśvā bhuvanāni harmyā citro vo yāmaḥ prayatāsv ṛṣṭiṣu ||
Devanagari rendered by HREEM from the edition's roman (IAST) text; the IAST is the edition's own.
Ye who with mighty powers have stirred the regions up, your coursers have sped forth directed by themselves. All creatures of the earth, all dwellings are afraid, for brilliant is your coming with your spears advanced.
Translated by Ralph T. H. Griffith (1896)
