Waters which come from heaven, or those that wander dug from the earth, or flowing free by nature, bright, purifying, speeding to the ocean, here let those waters, goddesses protect me. Rig Veda 7.49.2
I will declare the manly deeds of Indra, the first that he achieved, the Thunder-wielder. He slew the Dragon, then disclosed the waters and cleft the channels of the mountain torrents. Rig Veda 1.32.1
Then even nothingness was not, nor existence,
There was no air then, nor the heavens beyond it.
What covered it? Where was it?
In whose keeping was there then cosmic water, in depths unfathomed?
At first there was only darkness wrapped in darkness.
All this was only un-illumined water.
That one which came to be, enclosed in nothing,
Arose at last, born of the power of heat. Rig Veda 10.129.1, 3
