The control of breath is meant to extend life in many cultures, which I understand since it is oxygen what makes us decay (yet we can't live without it).

It is coincidentially the same cultures that believe in magic through chanting, and therefore ultimately in the vibration (ie. 'music is all') that physically and spiritually puts us together. It is this vibration that makes up the whole.

EDIT: And that is what we call the String Theory. It all makes sense. I can go to sleep now.
