∆ Feng Shui...Money Crystal Set~What's the principle behind Crystals? Cut-glass crystals take light and send it out in all directions. Where there's light there's energy. Hang a cut-glass crystal in a window and get a rainbow of lights on the floors, walls and ceiling, amd fill the room with energy. And because of the prismatic quality of the crystals the energy is separated into manageable parts. When the new opportunities arrive they will be easy to incorporate into your life.
