Feng Shui is widely known for making a living space "auspicious" or "inauspicious". More than just about making money or enhancing "good luck", there are aspects that determine what exactly is bad, how bad it is, and why it was bad to begin with.
1. The Main Door
The Main Door is one of the main features of a home that must be evaluated. It is essentially the Qi mouth of the house from which you can look out of, and whatever you see outside will determine the Feng Shui of your house.
If there is a tall structure, such as a lamp post within sight of the Main Door, Piercing Heart Sha may be present and can negatively affect health and careers.
Narrow gaps between houses visible from your Main Door represent Tian Zhan Sha (Crack in the Sky Sha), which is a highly undesirable external form. Avoid properties with these characteristics altogether.
Another negative feature to avoid is thick foliage over the Main Door, or shadows cast over the property in general. This can create Yin Sha, which can affect mental health.
The kitchen represents life and health. A badly located kitchen usually denotes poor health for the residents. The kitchen should always be towards the sides of the house, as locating a kitchen in the center, or Heavenly Heart, of the home symbolises giving the property a constant heartburn, creating instability and long-term health problems.
Do not put the stove in front of any door in the kitchen. This will create a mini T-Junction and the Qi will rush through the door, hitting the stove and imbuing the cooked food with Sha Qi.
Sleeping impacts our vitality and as such the bedrooms should be located in suitable sectors, based on the formulas in Eight Mansions, Xuan Kong Da Gua or Flying Stars. Rooms that are round, triangular or oddly shaped with sharp corners should be avoided. Instead, the bedroom should be in the shape of a square as it can help cut off negative Qi that impacts the room.
Look outside the Main Door of your property and observe the location of the drain. A drain that runs parallel to the Main Door is known as Cutting Feet Water. This can adversely block Qi from entering the property, cutting into the vitality of the house.
Watch out for curves on the roads leading to your property. Sharp curves are called Bow Formations and will cut the flow of Qi into a property.
Avoid properties that have narrow or wide alleys opposite them as they can cause either a Pulling Nose Qi problem or Sky Crack Sha problem, which are both difficult to correct once their negative effects have been applied.
Stay away from properties situated at T-Junctions. However, if a T-Junction just misses the property by a margin, you can usually counter its negativity by planting trees or plants to act as barriers to the bad Qi.
In conclusion, be prepared for the fact that almost any house will have a Feng Shui problem or two. Not every issue would be severe, but not every one of these problems can be fixed by a consultant either. The trick is to find a home without many problems and work from there.
