ब्रह्मणाग्नी वावृधानौ ब्रह्मवृद्धौ ब्रह्माहुतौ । ब्रह्मेद्धाव् अग्नी ईजाते रोहितस्य स्वर्विदः ॥४९॥
brahmaṇāgnī vāvṛdhānau brahmavṛddhau brahmāhutau | brahmeddhāv agnī ījāte rohitasya svarvidaḥ ||49||
Devanagari rendered by HREEM from the edition's roman (IAST) text; the IAST is the edition's own.
The two fires [are] increasing by bráhman, increased with bráhman, offered to with bráhman: kindled with bráhman, the two fires of the sky-finding ruddy one performed sacrifice.
Translated by William Dwight Whitney (1905)
