This bagua hanging features the yin yang eight trigram encircled with 12 Chinese horoscope animals on one side. On the reverse side is a mirror also decorated around it with images 12 Chinese zodiac animals. A bagua (eight trigrams) is a powerful cure in Feng Shui. This tool is widely utilized for safeguarding against very dangerous energies (such as the killing energy "Shar Chi" created from "poison arrows" pointing towards your home or workplace). These poison arrows come from many sharp-edged corners outside your home; lamp posts, buildings, t-junctions and other imposing structures. The types of issues that arise from this Shar Chi can be mild from arguments and tension, to the severe - sickness, accidents, and sometimes even fatalities. The bagua mirror is a very popular tool, used intensely in "Form School of Feng Shui", the oldest and first Feng Shui institution which was commenced in AD 960-1279, during the Song Dynasty. It has since become a common Feng Shui tool, because it is inexpensive, easy to use, and is very potent in repelling malicious spirits and intents that are after you. Hang it in the car's rearview mirror to drive away bad chi, chase away malevolent spirits, dissolve bad luck and prevent mishaps and accidents.
