"Ātman"

Ātman is a Sanskrit word which means essence, breath, and soul. It is the root from which many languages derived their word "to breathe. " It is said to be the life-force found within all beings, including the cosmos itself.

"Breath. Eyes and ears, with earth, water, air, and sky, with fire and with what is other than fire, with desire and the absence of desire... with everything - All this is Ātman and more." 

-Brihadaranyaka Upanishad, 9th century BC
