RV 5.12.2
ऋतं चिकित्व ऋतम् इच् चिकिद्ध्य् ऋतस्य धारा अनु तृन्धि पूर्वीः । नाहं यातुं सहसा न द्वयेन ऋतं सपाम्य् अरुषस्य वृष्णः ॥
ṛtaṃ cikitva ṛtam ic cikiddhy ṛtasya dhārā anu tṛndhi pūrvīḥ | nāhaṃ yātuṃ sahasā na dvayena ṛtaṃ sapāmy aruṣasya vṛṣṇaḥ ||
Devanagari rendered by HREEM from the edition's roman (IAST) text; the IAST is the edition's own.
Mark the Law, thou who knowest, yea, observe it: send forth the full streams of eternal Order. I use no sorcery with might or falsehood the sacred Law of the Red Steer I follow.
Translated by Ralph T. H. Griffith (1896)
