RV 10.120.8
इमा ब्रह्म बृहद्दिवो विवक्तीन्द्राय शूषम् अग्रियः स्वर्षाः । महो गोत्रस्य क्षयति स्वराजो दुरश् च विश्वा अवृणोद् अप स्वाः ॥
imā brahma bṛhaddivo vivaktīndrāya śūṣam agriyaḥ svarṣāḥ | maho gotrasya kṣayati svarājo duraś ca viśvā avṛṇod apa svāḥ ||
Devanagari rendered by HREEM from the edition's roman (IAST) text; the IAST is the edition's own.
Brhaddiva, the foremost of light-winners, repeats these holy prayers, this strength of Indra. He rules the great self-luminous fold of cattle, and all the doors of light hath he thrown open.
Translated by Ralph T. H. Griffith (1896)
