Vastu Shastra or Astrology, and Mantra Shastra are meant for the improvement of man`s social, intellectual, economic and health conditions. By following these Shastras, individuals can develop themselves. Buildings that are not built as per Vastu Shastra, they can be remodelled on its principles.
In constructing a house or a building, four factors must be taken into account: (1) Location of a well; (2) laying the foundation; (3) locating the front door; and (4) Griha-pravesam. Even if one has strictly gone by the Vastu considerations in these four phases, construction of the house must be started at an auspicious time, i.e., Muhurta.
Location of Well
The well must be located at the North and East side of the site. There is nothing wrong if another well such as a bore-well is also dug. Wells located in the South-East, South, South-West can be closed without any fear of sin. The remedy for this is to dig a deep well on the Eastern or the Northern side.
The compound wall should be built on all the four sides of the building. The walls may be of stone slabs or mud; they should be of the same size and height. No side should be vacant. At least a mud mound should be built. The compound walls should be higher, especially in the North or the East. In other directions, they must be even. There should be no growth in the North-East and South-East. If by any chance, it has a growth, it must be rectified. In any direction, if there is growth, we must be prepared to leave space in that direction. It can even be sold.
If there is a pit, it can be rectified by purchasing the land by its side. This extra land can be transferred to any member of the family. The same principle should be followed in the case of the house corners. If there is a compound wall between a factory and the residence, there must a window on the North-East, North and East. If this is not possible, at least an opening should be left in the North-Eastern or Eastern portion of the ceiling. If there are trees on the North and East side of the site, they can be removed after planting new trees on the South and West of the site.
The main door of the house should not be in the direction of (1) South-East, (2) North-West, or North side, and (3) South-West or South side. If it is already there, it should be closed, and there is no further option to it. There must be only one front door. There is nothing wrong in closing a door when there are two. There should not be three doors in a row behind the main door inside the house. If there are three such doors, one more door should be fixed, which may be made of aluminium or plywood. The same rule applies to windows also. The main door of the house facing the North, West, and East is important, and auspicious. But recent experience has proved that the main door should be facing the North side between North-East, in the East between the South-East, and in the South or between North-West. In West, North-West is very suitable.
The mirror has a special significance in our culture. It has been used from ancient times in temples and at the time of marriages and Grihapravesam. Care must be taken to fix the mirror so that the higher points or sections of the building should be reflected in the mirrors. It should not reflect South, South-East or North-West. Fixing mirrors and placing colourful flower pots adds to the beauty of the commercial centres and also strengthens the Vastu. The mirror helps ward off the evil eye (dristi). It is of no use to fix mirrors everywhere.
If there is a pillar, pole or tree or towers in front of the building and which is conspicuous, it is good to fix a mirror in the house to reflect it. The mirror must be so fixed that as far as possible it would not reflect South-East, North-West and South-West.
Fixing the Sri-chakra, Hanumana-chakra and Matsya-yantra help to mitigate the ill effects of Vastu-dosas.
Combination of Havana, Japa and prayer helps to rectify the defects of Vastu. The Vastu-havana should be performed before starting a new building to ward off the evil powers. Sudarsana and Ganapati Havanas should be performed for best results.
