It´s absolutely interesting. I wonder if we can do such things with the matter around us, what can we do to the cells in our body. I am a psychologist and I have seen many patients and above all my self, and I can notice perfectly well the effects of my emotions in my body. No matter if I express them or not. When an emotion remains not solved for a long time the first matter to which our mind, or unconscious mind, or however we want to call it, makes changes, is our own body and we definitely cannot avoid that from happening, and it is senseless to pretend to control the emotions, because they have a sense. The challenge is to learn to take their message, and our education and society, are a big obstacle between us and our emotions. And so forth, between us and our bodies.
