I know for sure this actually works.
No matter where in the World that person is ? All You have to simply do is clear your mind of everything else but 1 thought. That thought must be the Person You are calling. The Best way to do this is by constantly without any distraction repeat the Person's name in Your mind. It does'nt matter what You are doing ? Just keep the constant repetition in your mind. Also You don't necessarily need a strong faith in what You are doing, because what Your mind is doing has nothing to do with the physical self, it's purely spiritual. This must be done for a good length of time, until eventually the results You must receive is the voice of that Person calling Your name in Your mind. You may also become tormented with a stronger urge to see that Person. This must only be tried by all Who know the Power of the Mind & Spirit of the Human Body.
