Investigation on The Yin-Yang Token (1)
The Yin-Yang Token is a mirror used in Taoism that has a bronze mirror in the center.
It has the power to chase away evil and illuminate the truth.
The Yin-Yang token is octagonal and is inscribed with the eight trigrams, a mirror in the center, and the yin-yang symbol on the backside.
It is sometimes used in movies.
When energy is instilled in the token, it can unleash the energy chase away or destroy evil.
However, it is also said that simply reflecting light off the bronze mirror can yield the same effect.
