Feng Shui I looked for some loopholes marveling how a little convex mirror over the front door could drive away the bad chops of a neighbor or passerby. I marveled at how a handful of rice thrown high in the air could cleanse and bolster my health and peace of mind. If I am at the stove my back is to the door. I need a mirror to see behind or a chime hung with ribbons in multiples of 9 to protect me while I stir the soup. Chi can escape down your toliet or sink. So keep the bathroom door closed and the seat down.
