RV 1.121.7
स्विध्मा यद् वनधितिर् अपस्यात् सूरो अध्वरे परि रोधना गोः । यद् ध प्रभासि कृत्व्यां अनु द्यून् अनर्विशे पश्विषे तुराय ॥
svidhmā yad vanadhitir apasyāt sūro adhvare pari rodhanā goḥ | yad dha prabhāsi kṛtvyāṃ anu dyūn anarviśe paśviṣe turāya ||
Devanagari rendered by HREEM from the edition's roman (IAST) text; the IAST is the edition's own.
When the wood-pile, made of good logs, is ready, at the Sun's worship to bind fast the Bullock, Then when thou shinest forth through days of action for the Car-borne, the Swift, the Cattle-seeker.
Translated by Ralph T. H. Griffith (1896)
