RV 1.140.5
आद् अस्य ते ध्वसयन्तो वृथेरते कृष्णम् अभ्वम् महि वर्पः करिक्रतः । यत् सीम् महीम् अवनिम् प्राभि मर्मृशद् अभिश्वसन् स्तनयन्न् एति नानदत् ॥
ād asya te dhvasayanto vṛtherate kṛṣṇam abhvam mahi varpaḥ karikrataḥ | yat sīm mahīm avanim prābhi marmṛśad abhiśvasan stanayann eti nānadat ||
Devanagari rendered by HREEM from the edition's roman (IAST) text; the IAST is the edition's own.
Dispelling on their way the horror of black gloom, making a glorious show these flames of his fly forth, When o'er the spacious tract he spreads himself abroad, and rushes panting on with thunder and with roar.
Translated by Ralph T. H. Griffith (1896)
