RV 10.129.6
को अद्धा वेद क इह प्र वोचत् कुत आजाता कुत इयं विसृष्टिः । अर्वाग् देवा अस्य विसर्जनेनाथा को वेद यत आबभूव ॥
ko addhā veda ka iha pra vocat kuta ājātā kuta iyaṃ visṛṣṭiḥ | arvāg devā asya visarjanenāthā ko veda yata ābabhūva ||
Devanagari rendered by HREEM from the edition's roman (IAST) text; the IAST is the edition's own.
Who verily knows and who can here declare it, whence it was born and whence comes this creation? The Gods are later than this world's production. Who knows then whence it first came into being?
Translated by Ralph T. H. Griffith (1896)
