RV 2.1.3
त्वम् अग्न इन्द्रो वृषभः सताम् असि त्वं विष्णुर् उरुगायो नमस्यः । त्वम् ब्रह्मा रयिविद् ब्रह्मणस् पते त्वं विधर्तः सचसे पुरन्ध्या ॥
tvam agna indro vṛṣabhaḥ satām asi tvaṃ viṣṇur urugāyo namasyaḥ | tvam brahmā rayivid brahmaṇas pate tvaṃ vidhartaḥ sacase purandhyā ||
Devanagari rendered by HREEM from the edition's roman (IAST) text; the IAST is the edition's own.
Hero of Heroes, Agni! Thou art Indra, thou art Visnu of the Mighty Stride, adorable: Thou, Brahmanaspati, the Brahman finding wealth: thou, O Sustainer, with thy wisdom tendest us.
Translated by Ralph T. H. Griffith (1896)
