Our bodies and our brains are interconnected what we think affects our bodies and the cells of our bodies in return affect our thoughts. We have all felt thet sinking feeling in our bodies on hearing bad news and the lightness with good.

  

              Your worst enemy cannot harm you 

              As much as your own thoughts, unguarded.

              But once mastered,

              No one can help as much.
