Vastu dosha is a flaw or deficiency in the known characteristics of the eight directions. Remedial Vastu or corrective measures for any vastu faults should be attempted only after a proper understanding of the fundamental rules of vastu Shastra. The remedial measures can be divided into those applying to different stages of construction and can be implemented at either pre-construction stage or at post-construction stage.
At the pre-construction stage, the measures can be to rectify inauspicious shapes, slopes and depressions in the plot, observing proper pre-construction rituals, overcoming obstructions faced before construction or while construction.
Care should be taken and expert advice sought before purchasing a plot of land, a house, a building or an office space. Careful selection at this stage has long lasting benefits.
Strictly followed, Vastu Shastra forbids demolitions/ alterations or structural changes once the construction of a house is complete, deeming them to be a mutilation. At the post-construction stage, the corrective measures can be in the form of building additional structures, increasing the height of the building in relevant sectors, relocating the main entrance, etc. to balance the flow of energies in and around a structure. The measures at this stage also involve tackling obstructions and vedhas to the main entrance, interior planning and proper distribution of elements in the interiors. In addition, the use of astrological remedies like mantra, yantra and planting of auspicious trees and herbs around the building can yield positive results. Ideally, the best time for vastu advice is before a person starts building a house. That way his architect can incorporate Vastu advice into the design of fhe house. Unfortunately, most people don't do this. And they wake up years later wondering why their new house didn't give them the happiness they sought. In many cases, we find people's problems self-generated. They may be rich, living in a big house, but peace, happiness and good health elude them. The house they live in may be big, opulent and full of expensive things, but the usage is improper.
At times a change in fortunes happens when people carry out changes, renovations and extensions in the existing house or buy additional land adjacent to their property. Depending on the direction in which extensions are carried out the change can be for the better or for worse. As a rule, all extensions towards south, south-west, west, south-east or north-west of your site are considered inauspicious. Buy any additional land, which is to your north, east, or north east.
At times you buy a vastu-perfect site or house but over a period of time, the area surrounding your house changes. A changing city or neighborhood affects your fortunes. A tall building that comes up on your east blocks out sunlight. A nearby slum or a new temple on the same road as yours can spoil the vastu of your home. Suddenly increased traffic because of the road outside your house being connected to the main road, noise, smoke, blocked drains or shrinking parking space around your house, all affect the vastu of your home. Sometimes a rising road in front of your house or shop can bring bad results. Over the years, roads are re-metalled so many times that their level becomes higher than the house or shop. The elevation of the road can make the house look sunken. Most of the times this is very unlucky because Vastu Shastra says that land before a house or workplace should slope towards north or east. Elevated roads are good only in case of south and west facing plots and houses. Similarly, a newly constructed flyover in front of your office, shop or house can spoil your Vastu as it blocks sunlight and air.
In certain cases like these, extreme measures like shifting home or workplace are the only options available. People should not hesitate to leave one house and buy another if their first home deteriorates or its nearby environment suffers beyond repair. In certain cases, you may not have any control over any changes in your neighborhood environment. For example, you can have no say in what your ground floor neighbour does in his premises although it may affect you if you happen to live on any of the other floors. In one case, when the brother living on the ground floor started digging up a huge basement in the south-west of the house, it adversely affected his as well as the health and longevity of all his brothers living on the other floors of the same house.
Fortunately, in most of the cases such extreme steps as selling off your house or property are not required. As mentioned earlier, Vastu followed rigidly does not allow alteration or structural changes after the construction is complete as it is considered a mutilation. In the modern context also, structural changes are resorted to only in extreme cases. Just as a doctor does not prescribe surgery when antibiotics are sufficient, a Vastu expert does not recommend demolitions when easy and practical changes can bring about necessary balance and harmony in a structure.
Simple remedies like changing the seating arrangement, opening a window, changing an entrance or shuffling rooms between the family members can bring about positivity, happiness and prosperity in a household.
