When we are vibrating high, we are getting closer to our wish coming true. But, when we are vibrating on a low frequency, that is when we are stepping away from our wishes, dreams, and desires.
During the visualisation, the crucial thing is that you sense the emotion of having that money in your hands. Because when you experience the feeling of having money, your emotions move higher, you are vibrating highly. And when your vibration is high, it is just a matter of time when the Universe will send you the thing you thought about in your visualisation.
