The fundamental principle is the same as that of the ESP tape. Since I created it, it has become the source of constant surprises. Supernatural power is a power beyond physics. In other words, it is a power which cannot be explained by contemporary human science. This is where the mystery and the potential of supernatural power lies.
Supernatural power has a long history.
No doubt, since human beings appeared on the face of this earth, supernatural power has been one of the riddles of humankind. A good example of this is the people living in antiquity and through out the middle ages who brought into their lives and made use of invisible powers of many shapes and forms. However, all this changed when human beings became conscious of science. To put it another way, when man came to desire rapid progress, his circumstances changed. There is no question but that the world has progressed.
