The Eight Directions of the compass are south, southwest, west, northwest, north, northeast, east, and southeast.  Each is associated with a different kind of Chi Energy.  Each direction is also linked with one of the five elements, a symbol of the natural world, a family member, a nine ki number, a colour, a time of day and a season.  A distinctive type of energy is found in different sectors of a home, a room or a landscape.  These sectors are defined by their direction from the centre of the home, room or landscape, which is determined by a compass.  A room in the north of your home, for example, will carry the chi energy of the north; but different parts of that room will also held some elements of the chi energies of the other directions.   

The Eight Directions are a further refinement of Yin and Yang and the Five Elements, and provide eight different kinds of chi energy to define.  There is also the centre, which has it own characteristics, and which in terms of positioning rooms.   

There are several approaches you can take to allocating the rooms.  You can match the room's activities to areas with supportive chi energy, or you can target areas of your life you wish to improve, identify the kind of chi energy that will be helpful and allocate the rooms so that you spend most of your time there, or you can use the Eight Directions to solve a particular problem.
