RV 10.88.6
मूर्धा भुवो भवति नक्तम् अग्निस् ततः सूर्यो जायते प्रातर् उद्यन् । मायाम् ऊ तु यज्ञियानाम् एताम् अपो यत् तूर्णिश् चरति प्रजानन् ॥
mūrdhā bhuvo bhavati naktam agnis tataḥ sūryo jāyate prātar udyan | māyām ū tu yajñiyānām etām apo yat tūrṇiś carati prajānan ||
Devanagari rendered by HREEM from the edition's roman (IAST) text; the IAST is the edition's own.
Head of the world is Agni in the night-time; then, as the Sun, at morn springs up and rises. Then to his task goes the prompt Priest foreknowing the wondrous power of Gods who must be honoured.
Translated by Ralph T. H. Griffith (1896)
