Dear Master Lee, I know you get asked so many questions about bagua mirrors - but I am afraid I have some which have not been covered yet in your very extensive forum. 1. My company is housed in an office building, where our main door is glass and surrounded by a very thin aluminium frame. I cannot fix a bagua mirror to it without some part of the apparatus being obscured. Either I can, A: fix the bagua mirror so that the bottom of the mirror is flush with the frame (allowing the door to freely swing in and out); or I can B: put the bagua mirror on the front of the glass door, meaning that the bagua mirror will be affixed to the front of the glass and moving with it. The problem with A is, since the frame is so thin and there is acoustic roof tile right above the frame, the heaven trigram of the bagua mirror will be obscured. Basically everything above the central mirror of the bagua will be above the acoustic tile. My question is, which is the preferable option, or are both extremely undesirable? 2. The front of my apartment directly faces not 1, but 2 lift shafts. I have read in multiple places that a convex bagua mirror is to be placed on top of my front door frame. However, at the moment I have a concave mirror placed because I thought the concave is the least offensive bagua mirror choice. In your expert opinion, is it a must to use convex infront of elevator shafts, or is the convex acceptable? Thank you so much Master Lee for taking the time to read and hopefully answer my questions, however short your answer may be. Luck has been very very bad for me and I am doing everything I can do affect a turn around. Change starts with ones self but I am also trying to change my environment. My best regards to you.
