RV 4.21.1
आ यात्व् इन्द्रो ऽवस उप न इह स्तुतः सधमाद् अस्तु शूरः । वावृधानस् तविषीर् यस्य पूर्वीर् द्यौर् न क्षत्रम् अभिभूति पुष्यात् ॥
ā yātv indro 'vasa upa na iha stutaḥ sadhamād astu śūraḥ | vāvṛdhānas taviṣīr yasya pūrvīr dyaur na kṣatram abhibhūti puṣyāt ||
Devanagari rendered by HREEM from the edition's roman (IAST) text; the IAST is the edition's own.
May Indra come to us for our protection; here be the Hero, praised, our feast-companion. May he whose powers are many, waxen mighty, cherish, like Dyaus, his own supreme dominion.
Translated by Ralph T. H. Griffith (1896)
