RV 10.139.6
सस्निम् अविन्दच् चरणे नदीनाम् अपावृणोद् दुरो अश्मव्रजानाम् । प्रासां गन्धर्वो अमृतानि वोचद् इन्द्रो दक्षम् परि जानाद् अहीनाम् ॥
sasnim avindac caraṇe nadīnām apāvṛṇod duro aśmavrajānām | prāsāṃ gandharvo amṛtāni vocad indro dakṣam pari jānād ahīnām ||
Devanagari rendered by HREEM from the edition's roman (IAST) text; the IAST is the edition's own.
In the floods' track he found the booty seeker: the rocky cow-pen's doors he threw wide open. These, the Gandharva told him, Rowed with Amrta. Indra knew well the puissance of the dragons.
Translated by Ralph T. H. Griffith (1896)
