RV 4.18.1
अयम् पन्था अनुवित्तः पुराणो यतो देवा उदजायन्त विश्वे । अतश् चिद् आ जनिषीष्ट प्रवृद्धो मा मातरम् अमुया पत्तवे कः ॥
ayam panthā anuvittaḥ purāṇo yato devā udajāyanta viśve | ataś cid ā janiṣīṣṭa pravṛddho mā mātaram amuyā pattave kaḥ ||
Devanagari rendered by HREEM from the edition's roman (IAST) text; the IAST is the edition's own.
This is the ancient and accepted pathway by which all Gods have come into existence. Hereby could one be born though waxen mighty. Let him not, otherwise, destroy his Mother.
Translated by Ralph T. H. Griffith (1896)
