We make affordable the Feng Shui cures. For your house and/or office. The Austrian crystals balls adjust the flow of energy and activate any area instantly with the reflective light and rainbows. We recommend to use this size for small windows, for regular or large one please select 30mm or 40mm. Hung in windows, crystals can bring chi energy from the outside into dark or stagnant areas of your home or office, as well as energizing particular sectors for creating desired positive results. For example, a crystal placed in the south-east, north-west, or center of an environment can aid in stimulaing prosperity. Crystals can also be used to diffuse negative or "sha" chi that results from a sharp corner, beam, or hard edged column. By hanging the crystal near these structures, "knives" or "poison arrows" are dulled and their adverse effects are diminished.
