RV 1.185.1
कतरा पूर्वा कतरापरायोः कथा जाते कवयः को वि वेद । विश्वं त्मना बिभृतो यद् ध नाम वि वर्तेते अहनी चक्रियेव ॥
katarā pūrvā katarāparāyoḥ kathā jāte kavayaḥ ko vi veda | viśvaṃ tmanā bibhṛto yad dha nāma vi vartete ahanī cakriyeva ||
Devanagari rendered by HREEM from the edition's roman (IAST) text; the IAST is the edition's own.
Whether of these is elder, whether later? How were they born? Who knoweth it, ye sages? These of themselves support all things existing: as on a car the Day and Night roll onward.
Translated by Ralph T. H. Griffith (1896)
