Why do we need to be mindful of balance? Like a well-balanced wheel, the center is the point of equilibrium. When the center is off the wheel will wobble and fall because the internal centrifugal force will not push substantially against the outside forces of the tire. The ride will be bumpy at best causing the bike to behave in exaggerated ways.
As in our own thoughts, feelings and reactions, if we are not centered and live in extremes, our behavior will be out of proportion. We are connected with soul by being centered. When soul is centered we are operating from a point of balance.
