'As clouds of smoke proceed by themselves out of lighted fire kindled with damp fuel, thus verily, O Maitreyi, has been breathed forth from this great Being what we have as Rig-veda, Yagur-veda, Sama-veda, Atharvangirasas, Itihasa, Purana, Vidya, the Upanishads, Slokas, Sutras, Anuvyakhyanas, Vyakhyanas, what is sacrificed, what is poured out, food, drink, this world and the other world, and all creatures. From him alone all these were breathed forth.

In plain words: Just as smoke rises by itself from a fire of damp wood, all the sacred books, stories, teachings, rituals, food, drink, this world, the next world and all creatures came out from the great Being like breath. Everything comes from that one source.
