I happen to believe that disease has an energetic root. It is hard to explain but as I research further in the field of Energy Medicine I cannot help and wonder whether the whole medical system has it all wrong. Last time I check we are not only "flesh" made up of molecules and cells. Our biochemistry is one part of who we are. But new areas of scientific exploration are looking closely at the relationship of biochemistry and biophysics. Humans are energetic beings. NO ONE can deny that. Our molecules are an aggregate of sub-atomic energy/particles. The "new" medicine is beginning to explain the ability of the human body to "self-heal" But how does that work? Here are a couple of links that may help you expand your understanding of this "new medicine"
