Started another thread because John's post above was concerning martial arts. Some martial arts are spiritually based - particularly Tai Chi and Aikido, which are designed to enhance and manipulate the chi. My former husband studied aikido and talked about the supposed power one could develop, like holding a large man down with a little finger (this was not done through physical strength). He saw this done. Some make distinctions between the "hard" martial arts, which are more physical in nature and intent like karate, and the "soft" martial arts, which are very spiritually rooted. If you look at some of the teachings in these areas, you find they are very spiritual. I've also talked to Christians who were involved in Tai Chi and the "powers" and sensations they got from this started freaking them out. I also had experiences of this energy when I was doing Eastern meditation and involved in the occult for a number of years. It became so strong that I could sense it around me (it was like an electrical current constantly on) and from other people. It went away after I trusted Christ. Due to my experiences with this force, I know it was not from God. It's tied directly into the occult and it is not unknown by those who get involved in the occult.
