During my practice, I have witnessed on many occasions, that mirrors are kept directly opposite the main door of the house. Such a practice is very harmful as this results in the reflecting back of the good chi (energy) that enters from the main door. It is reflected back and escapes out of the door !

I have even come across cases when the client had been advised by an inexperienced consultant to affix a big mirror opposite the main door because the entrance had a blank wall opposite it!

An entrance to a blank wall is bad, but this type of correction to create depth by means of a mirror, is very wrong in my opinion. The right correction, is to affix a scenery of depth on the opposite wall. It can be a scene of a road or path meandering and going deep into the forest, mainly to create the feeling of depth symbolically.
