`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, Samaveda, 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.
