What is the most precious gem in the world? Certainly this life is precious — the opportunity to be alive is an irreplaceable gift — but can we really appreciate this life for what it is? If we want to find the precious gem in our life, where do we begin? Where do we look? Should we look outside somewhere, or should we look inside? And what does it mean to look inside? Are we really going to find something of value in our body, perhaps in our head or our belly? By pursuing these questions with your whole body and mind, you can discover the truth …. for yourself. But no matter how hard you try, you will never find what is truly precious if you look outside of yourself. You have to look within.
