Being still: One should become aware of the integration of body and mind. It should be remembered, however, that in general the mind rules the body. The mind moves first, and then the body follows. So your body language is totally dependent on your mental function. Try to raise your arm without first thinking about it. It cannot be done. In order to raise the arm you must first think “Arm, raise” and then send message through the nervous system from the brain to the arm. The arm will not move until the mind tells it to do so.
