The reason visualization is so powerful is that as you create pictures in your mind of seeing yourself with what it is you want, you are generating thoughts and feelings of having it now. Visualization is simply powerfully focused thought in pictures, and it causes equally powerful feelings. When you are visualizing, you are emitting that powerful frequency out into the Universe. The law of attraction will take hold of that powerful signal and return those pictures back to you, just as you saw them in your mind.
