I remember years ago, I saw a documentary on, Cellular Communication. In essence, what was done is a the scientist scraped some cells from the inside of several participants mouths and placed them in a petre dish. They connected those cells to a lie-detector type looking device. As the participants were introduced to different stimuli, naturally their bodies would react. Finally, they let the subjects walk out of the building on to the street, as the they came in contact with other people or other stimulus, those cells continued to respond.
Psychokinetic ability is no different.
These abilities are very natural. Some research shows there is a lot of activity in the cortex of the brain in relationship to this. On phasing phenomenon is photon related manifestation of energy and light. There is also a good deal of illusion as well. One must be able to discern the reality of both.
