Bagua mirror convex

The first feng shui rule for using the bagua mirror is that it should never, ever be used indoors.

The second feng shui rule for using the bagua mirror is that you use it only if there is bad feng shui energy - Sha Chi or Si Chi - facing your home or business. The feng shui bagua mirror is not a decoration feng shui item and should not be used as such.

If you do find yourself in a position that requires subtle protection of your home or office from potentially dangerous Sha Shi feng shui energies, (sharp or attacking structures pointing at your home), or bad energy coming from your neighbours, you may choose to use the bagua mirror.
Best is to place a feng shui bagua mirror when advised by a professional feng shui consultant. Traditionally, a feng shui bagua mirror is placed above the front door or above a big window that is facing questionable outside energies.

Using outdoors: Please hang your baqua mirror as much as possible on a protected place, to protect it against atmospheric influences.

Feng Shui
Feng Shui (pronounce as: fang shouee) is an over 3,000 years old philosophy, teaching how environmental factors influence our well-being, and also how negative influences may be altered into positive ones. Feng Shui aims to adapt our living or working environment in ways that stimulate a harmonious flow of Chi (life force). In Chinese philosophy, it is all about harmony and balance between the complementary forces of yin and yang, like male and female, etc.
