RV 10.129.2
न मृत्युर् आसीद् अमृतं न तर्हि न रात्र्या अह्न आसीत् प्रकेतः । आनीद् अवातं स्वधया तद् एकं तस्माद् धान्यन् न परः किं चनास ॥
na mṛtyur āsīd amṛtaṃ na tarhi na rātryā ahna āsīt praketaḥ | ānīd avātaṃ svadhayā tad ekaṃ tasmād dhānyan na paraḥ kiṃ canāsa ||
Devanagari rendered by HREEM from the edition's roman (IAST) text; the IAST is the edition's own.
Death was not then, nor was there aught immortal: no sign was there, the day's and night's divider. That One Thing, breathless, breathed by its own nature: apart from it was nothing whatsoever.
Translated by Ralph T. H. Griffith (1896)
