The Bagua mirror, with concave and convex surfaces, serves as a protective shield against negative external influences such as poison arrows, sharp structures, or aggressive energies. The Chinese symbols further empower the mirror by invoking universal balance.

Depending on its type—concave (to absorb) or convex (to reflect)—this mirror must be placed very carefully, usually outside your home or workspace. With the help of a professional, you can ensure it's aligned to neutralize negativity without unintentionally reflecting it back inwards.
