If we allow the term, or idea of, energy to encompass a large aspect of our definition of qi than I believe acupuncture has proven to be effective for thousands of years.  The manipulation of needles at specific points on the body has been shown to alter the energetic pathways of the body, allowing the immune system to function properly and heal itself.  Acupuncture can effect hormonal imbalances, influence enzymatic pathways, stimulate the nervous system, and effect PH levels inside the human body.  These energetic shifts optimize our health and create a more harmonious environment for our bodies and our minds.

Whether Kirlian photography shows the existence of an "aura" or just a "corona plasma discharge" caused by water in the air around the objest, it shows that on some level our energetic existence extends past our physical bodies.  We interact verbally with other people all day long but rarely do we stop to think about how we effect others on a more subtle level.  Kirlian photography to me represents this presence that exists outside of our visual field.  Possibly Kirlian photography is a reminder that our words and expressions have an impact on everything and everyone we come in contact with.  A light that can either inspire happiness and creativity, or leave a lasting mark of fear, anger, or resentment.

Our intentions have a direct affect on our health and this idea is no longer held only by practitioners and supporters of so called "alternative" medicine.  Many double blind placebo studies have shown that when people believe they're taking a medication for some illness, they often will have healing results.  This phenomenon has even been observed when the subjects knew for a fact they were taking a sugar pill and not a medication for high blood pressure.  It has been hypothesized that by just focusing their intention for a brief moment on their blood pressure the subjects in the study altered their internal chemistry and received health benefits.
