" The infinite is Brahman. From it, from this Self, space came to be; from space, the wind; from the wind, fire; from fire, water; from water, earth; from earth, the plants; from plants, food; and from food, the body of men. This body of man, composed of the essence of food, is the physical sheath of the self."
