The main entrance to your home(whether that be your front door,side door,garage door etc)is a very crucial area in which to practice good Feng Shui.This carries alot of your home's energy in & out of your home.
The door used here should be wide enough to let positive chi flow freely through your entrance.Any statues or shrubs you might choose to decorate your entrance should clearly be placed out of the way and not blocking the flow in &/or out of these doors.
Your door should be sturdy & working properly.A sqeak in your door,a door that gets stuck or a door with a 'trick' doorknob or lock should be replaced or repaired.The little annoyance or aggrivation that these little mishaps in doors can have immediatley are carried into your home with you dispensing negative energy upon entering.
The first wall you see upon entrance of your home should never be blank.Feelings that are triggerd by being greeted by a bare wall are usually negative.Feeling stuck or feeling like your constantly running into a brick wall per say.A mirror,a fountain or landscape art would be good here.This will open up the space freely & prevent blockage.
