It is important that the flow of Chi from the front to the back of your home is not hindered. It is also best to have it flow through in a meandering path and not a direct line. Entrance ways off the street or through your garden to the front door will determine the qualities of Chi that flow into your home. Therefore it is important to use curved pathways or garden beds. Breaking up the direction of pavers to allow curved lines will also help. A birdbath, fountain or a small pond along the way will bring balance and improve the qualities of Chi.
Too large a doorway will allow Chi to escape from your home. If this is a problem for you it can be easily counteracted by placing a windchime outside the door. This will also discourage Sha (negative energy) from entering your home. Too small a doorway will not allow enough Chi to enter the home, but placing a mirror on either side of the door or on a wall opposite the door will help to fix the problem.
If the back door can be seen from the front door, Chi can flow straight through your home without circulating. Placing a large potted plant or a screen in between the two will break up the straight lines and help to deflect Chi.
The entrance hall is most auspicious in terms of Feng Shui as it is the place where one might pause upon entering or leaving the home, thus being energized by the Chi that flows through it. Entrance halls that have no windows or doors leading from them or are enclosed in some way can cause Chi to stagnate. Again mirrors or a ceiling fan or maybe a small water fountain will solve this problem.
