The best arrangement of furniture is in a circular, square or octagonal grouping in the middle of the floor to allow for the flow.
Do not block the door with furniture. This will only hinder the entry and movement of energy. Do not place the chairs so that anybody shows their back to the door. It adds to their vulnerability. The chairs as a last resort may be placed at right angles to the door.
If one chair has to have its back toe eh odor, then place some potted plant behind the chair. The number of seating in a living room should add up to an even number.
Every guest should have a clear view of the door. A guest feels sub consciously honored if he is offered a chair farthest form the entrance.
Try to avoid L-shaped arrangements of furniture does not allow for the circulation of energy.
In many cases, the living room has doors on the opposite walls. This is to enable movement from room to room. If your living room is also a passage way into the home, do not place, the group of furniture between two opposite doors.
