If you are in desperate need of physical strength, that dark force will try to weaken you physically. If you are in desperate need of money, that dark force will create financial problems for you. If you are in need of technical support, it will create technical problems for you. If you are in need of intellectual support, it will try to keep away from such sources. If you are in need of information, it will shut down all communication links. But these are not problems in my life which comes in way of execution of this device. So that dark force "invented" some other problems for me. That dark force knew/know which things can crash my moral down to zero and that dark force is striking right on targets with perfect timing so that my moral does not get a lift. You people are just one of these targets. That dark force is controlling your mind and trying to keep you away from understanding simplicity of this device. http://www.geocities.com/actiondevice -Abhi.
