"The body serves the mind, and the mind serves the Spirit. This is the true order of things, but it is not the order that you experience currently. The order that you experience currently is that your mind serves your body, and your Spirit serves your mind. When you are concerned primarily with survival and personal fulfillment, you are concerned with everything serving the mind and the body. You will use your relationships for this purpose and will either knowingly or unknowingly require that God serve this purpose as well." 
The body as a temple
"You will learn to share your body by recognizing the relationships that it contains. No longer will it be a prison house in which you think you live and die, but rather a temple where your loved ones come to join you in peace and matrimony."
The body as an instrument
"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."
