I purchased two BaGua mirrors, one convex and one concave. I was going to hang them together in my house on my wall but now I read they are to be hung outside. Which one is better tohang and where does it go? If I hang it inside can it be facing out a window or does it need to actually be outside? Can I hang them both together outside or only one at a time? Can I hang it on a railing if there is no space to be hung over the outside door? I am trying to improve positive energy in and around my house. Thank youin advance for your assistance.
