Try this small experiment (Not black magic but scientific): Requires five people (adults). One should be sitting on a chair comfortably (back straight) in the center while the four should be standing on 4 corners. The room should be quite and no giggling. Calm your minds. Thereafter, one person should keep his/her left hand palm facing downwards just above the head of the one sitting.(It should not touch the head but just 3-4 inches above). This should be followed by a quick succession of all the others keeping their left palm over the hand of the one before them - hands should touch and energy focussed. After this pile the right palm in the same fashion. Than take the hands away rhytmically one by one and not in a hurry. Immediately after that touch the four corners of the chair with index finger trying to lift it. After sometime (almost 11-12 times of repeating the same)the telepathic energy gets foccused and you can lift a person along with the chair with just 4 index fingers. This is not black magic but the collective mental energy of 4 people.
