"Your body is a beautiful instrument. It is marvelous in what it can do. But its real value is determined by what it serves. If it serves a conflicted agenda of the mind, then the body will do destructive things to itself and to other bodies in the world around you." 
"The purpose of the body is not to be beautiful. It is to be an instrument of communication, to be a vehicle and to participate in a physical world in a physical reality. Like an automobile, if it can get you where you need to go, it has done its job." 
"The car is supposed to serve the driver, not the other way around."
