Now I have taught classes in Kinesiology, which is the science of how the body moves. And we know from Kinesiology and from Anatomy, that the body can only move when it gets a picture from the nervous system. And that applies more to golf than any other sport that I know about.
The mind is a computer and where the mind leaves, the body will fall because the nerves are all attached to the muscles in your body and the muscles are attached to the skeletal system. So when this messages relayed from our mind down through the nerve, the body has to fall the picture that's in the computer of your mind.
Remember this about the mind, that a mental command brings a physical demand.
