Brahma means the vast, infinite principle. The element of sound emanated from this infinite expanse of Brahma. From sound emerged air, fire from air, wind from fire, earth from wind, ocean from earth, food from oceans and finally, humans from food. Ponder this sequential cycle and you will arrive at the truth that man (Purusha) has emerged from the infinite Brahma.
