RV 7.78.3
एता उ त्याः प्रत्य् अदृश्रन् पुरस्ताज् ज्योतिर् यच्छन्तीर् उषसो विभातीः । अजीजनन् सूर्यं यज्ञम् अग्निम् अपाचीनं तमो अगाद् अजुष्टम् ॥
etā u tyāḥ praty adṛśran purastāj jyotir yacchantīr uṣaso vibhātīḥ | ajījanan sūryaṃ yajñam agnim apācīnaṃ tamo agād ajuṣṭam ||
Devanagari rendered by HREEM from the edition's roman (IAST) text; the IAST is the edition's own.
Apparent eastward are those lights of Morning, sending out lustre, as they rise, around them. She hath brought forth Sun, sacrifice, and Agni, and far away hath fled detested darkness.
Translated by Ralph T. H. Griffith (1896)
