Rig Veda 9.45

sa pavasva madāya kaṃ nṛcakṣā devavītaye indav indrāya pītaye

Flow, thou who viewest men, to give delight, to entertain the Gods, Indu, to Indra for his drink.

sa no arṣābhi dūtyaṃ tvam indrāya tośase devān sakhibhya ā varam

Stream to thine embassy for us: thou hastenest, for Indra, to The Gods, O better than our friends.

uta tvām aruṇaṃ vayaṃ gobhir añjmo madāya kam vi no rāye duro vṛdhi

We balm thee, red of hue, with milk to fit thee for the rapturous joy: Unbar for us the doors of wealth.

aty ū pavitram akramīd vājī dhuraṃ na yāmani indur deveṣu patyate

He through the sieve hath passed, as comes a courser to the pole, to run Indu belongs unto the Gods.

sam ī sakhāyo asvaran vane krīﾱantam atyavim induṃ nāvā anūṣata

All friends have lauded him as he sports in the wood, beyond the fleece: Singers have chanted Indu's praise.

tayā pavasva dhārayā yayā pīto vicakṣase indo stotre suvīryam

Flow, Indu, with that stream wherein steeped thou announcest to the man Who worships thee heroic strength.
