Mirrors are said to have the ability to cure anything in feng shui. This concave mirror, makes you realize that your thoughts and actions are reflected back to you by others. So, make sure you place it in such a way that it reflects views that are pleasant. This should be placed or hung outside the house or office to reject or push away negative energy that might be approaching the house. If it is hung above your front door, it will keep attracting good Chi energy into your house or office. If the view is beautiful outside, then attracting the positive Chi is the best thing to do.
