During my studies of martial arts I have experienced / felt the Chi energy. As humans we need to label everything. What it is called makes no difference. Feeling the energy move to my hands and creating heat . My mental facilities and feelings in my body changing. We are beings that house electric energy. The martial arts training helps to teach focus. I think during a situation when mind and body come together that energy moves to the area it can be used if needed. With me it is not a conscious thing. It will appear when I am teaching a lesson about protecting one's self . Especially when it is about a big person going after a smaller one. I think we all have it. But many ignore it.
