Balance often comes from the feet.  And if they ache, are twisted, or if your stance is off center then so is your square.  Think of you square as your torso only don’t forget your hips, shoulders, and the main objective: to balance your head.  If your physical square is off center then its just a matter of time until your spiritual and psychological square loose their center as well. When ever illness is present it is a good idea to assess your square.  Are you centered?   If not what can you do to regain it?  Consider basic exercises like walking around an object, between two different objects, or just moving out of the way as if someone is walking toward you on a crowded street.  Focus on keeping your square centered and on breathing (make sure you do both).   While these sound like simple exercises for many of us they are not.  Fortunately with a little bit of patience and perseverance you will catch on quick enough.  You might also discover that being in control of your square brings benefits that were unexpected.   Create your own system of health and personal protection. Experience Freedom.
