A Bagua Mirror is a traditional Chinese Feng Shui tool used to deflect negative energy or sha qi and promote positive energy or sheng qi. The term "Bagua" refers to the eight trigrams used in ancient Chinese philosophy and divination, which represent different aspects of life and nature. The Bagua Mirror typically consists of a round mirror encircled by an octagonal frame divided into eight sections, each representing one of the eight trigrams.
The mirror is believed to have protective properties and is often placed outside homes, businesses, or specific areas to ward off negative influences and promote harmony. The concave mirror is said to absorb and neutralize any negative energy directed towards it, while the octagonal frame with the trigrams acts as a symbolic shield, deflecting the harmful energy away.
