" The most powerful way to use the mind-body connection to improve your physical and mental health is through guiding your autonomic nervous system (ANS). Every time you calm the ANS through stimulating the parasympathetic nervous system (PNS), you tilt your body, brain, and mind increasingly toward inner peace and well-being. "
