A feng shui bagua mirror (pa kua mirror) is a special octagon-shaped mirror. It is a powerful cure to protect against negative energy and create good fortune and harmony. This type of mirror protects a house or place of business from the negative energy. A Feng Shui bagua mirror is used outside of a home to redirect energy. A general guideline is that they should never be hung inside a home or business and only be used on the outside. This mirror is used to reflects negative bad energy away from house and home Examples of when to use a BaGua Mirror: 1) If your home or business is at the end of a T-Intersection, 2) if you have a corner or sharp object pointing at the front door, 3) if you are experiencing unpleasant energy from a particular area around your home or business.
