Rasaji once asked Bo-Yang, his master, What really is Tai' Chi Gung? 

Bo-Yang replied,  "Tai' Chi Gung is the owner's manual for the physical body."

Think for a moment.  When you buy a new vehicle, you receive a nice slick owner’s manual.  You may never really look at it, but it is filled with information about how your vehicle is designed to function, what it can do and how to maintain it. You may not understand it or use it, but at least you have it. On the other hand, most human beings sort of squeegee in to the earth, they don’t have any real idea how the body works or what it is truly capable of. And they often don’t manage to learn much about it until some part of it doesn’t work correctly.

The physical body is a miracle. It is a miraculous gift of God. But in truth, we’re on the “rent with an option to buy” plan. We must learn to use it properly or we’ll eventually lose it. What is truly profound about Tai’ Chi Gung, is that it can equip every individual who adopts the practice with the knowledge and resources to rebuild, restore, maintain and improve their basic health function on a daily basis. Within the eight aspects of Chi that follow, you’ll come to understand the profound regenerative power that is waiting to be discovered within your own body right now.
