This is a special concave bagua mirror where the usual eight trigrams surrounding it are being replaced with the rings seen in a Luo Pan. It is nonetheless as potent and powerful as the traditional bagua mirror and is pretty common nowadays.
The Bagua Mirror is a traditional Feng Shui cure commonly used for protection against the most malignant type of energies – the killing energy or Shar Chi generated from ‘poison arrows’ directed to your house, shop or building. Poison arrows can manifest in many forms: offending poles, lamp posts, trees, large building, edges of building, a road headed towards you, T-Junctions, escalators and other imposing structures, infrastructures or landscape in front of your house or workplace’s main door, the ‘chi’ entry point. At its best, this kind of killing Chi could result in constant arguments, depression and minor misfortunes, and at its worst brings severe sickness, mishaps, accidents and even death in the household if it is not promptly dealt with. Baguas could also repel evil spirits and people with bad intentions towards you.
A Concave Bagua is used to absorb Shar Chi and preventing it from entering the house or building. A Concave Bagua is recommended over a Convex Bagua because a Bagua with a mirror that curves outward (convex) would deflect and reflect all harmful chi away. This could inadvertently harm your neighbors and surroundings. For example, if you place a convex Bagua to deflect the Shar Chi coming from an imposing tree, the tree will not grow well and will even die! While the Convex Bagua is the most powerful, a Concave Bagua will usually be sufficient to do the job and not create bad karma for you. Unless the Shar Chi is very strong or you are very sure that placing a Convex Ba gua will not harm others, a Concave Ba gua would be a better choice.
Hang the Concave Luo Pan Bagua above the door facing the poison arrow pointing to you. If you have a porch, you could put it on top of the porch. REMEMBER that Baguas can only be placed outdoor. It SHOULD NEVER be hung indoor or it will do great harm.
