yó adribhít prathamajā́ r̥tā́vā bŕ̥haspátir āṅgirasó havíṣmān |
dvibárhajmā prāgharmasát pitā́ na ā́ ródasī vr̥ṣabhó roravīti ||1||

Served with oblations, first-born, mountain-render, Angiras' Son,
Brihaspati the holy.
With twice-firm path, dwelling in light, our Father, roars loudly, as a bull, to earth and heaven.
