Every home could probably use a bagua mirror to repel negative energy and attract positive energy. Bagua mirrors combine the energies of a mirror and a bagua map.
The Bagua (or Pa Kua) consists of eight sacred emblems--each representing a different area of one's life. Arranged in an octagonal pattern, the Bagua represents balance and the smooth flow of energy.
A concave mirror collects negative energy and absorbs it. This might be preferable if there are negative energies lurking about.
A convex mirror can expand positive energy but it can also reflect back negative energy. You don't want these undesirable energies flying about so they need to be placed near an entry or exit point like a door or window.
