Please kindly verify this (got it from another website): There's alot of supersition surrounding the bagua symbol. Even the average Chinese person assumes that its a "mirror" to reflect back evil. It doesn't really reflect back "anything". The bagua you see on these mirrors is the Fu Xi Bagua, which is the first bagua (the bagua changes like the I-Ching). It is the bagua of Death, of the Invisible World, before the world manifested into the mundane. Its purpose is to take negative chi and put into its perfect state, which is, in Taoism, nothingness. If you look at the Fu Xi Bagua you will see the chyan trigram at the top and the kun trigram at the bottom. Jen trigram is in the bottom left and gen trigram is the bottom right, etc. The lines of all opposite trigrams add up to 9, which means completion. All trigrams are complimentary opposites symbolically. If you wish to turn an external shar chi into "nothingness" you may turn it upside down so that chyan is at the bottom. Chyan, which often symbolizes a sword will fight back the shar chi. You place it inside the house BUT the mirror is turned around against the wall as though its power is going thru the wall out to the external shar chi. That way you dont see the bagua inside your house. Because, we all know, one shouldnt never see a bagua inside a house. Thanks John.
