The principles of orientation in Maharishi Sthapatya Veda are based on the position of the sun, considered by MVS to be the most powerful natural influence on Earth. Aligned with the rising sun, an East-facing house is considered most auspicious for the building's inhabitants. The other three cardinal directions also have their corresponding influences. Homes with entrances facing west invite "poverty, lack of creativity and vitality",and "anxiety, depression, bad luck and even criminal tendencies". According to the MVS official website, the west direction is said to have the influence of poverty and lack of vitality or creativity, the north direction has the influence of prosperity and happiness and the south direction has the influence of negativity, problems and suffering.
When a house for a particular individual is being designed, the placement of the building and its rooms are carefully planned according to their intended usage and the influence of the sun as it moves throughout the day. Rooms are placed to "take in the sun's light as it passes overhead". Windows and skylights are also used to allow as much natural sunlight as possible to enter the building.An aspect of MVS called "Vastu Vidya" determines the places in the building that are used for generating and storing natural elements like fire and water; heating and plumbing Bathrooms fixtures such as sinks and mirrors also have a particular placement according to MSV.
The rule for proper proportion in MVS is symmetry. Symmetry is orderly and in a symmetrical system every part is related to every other part. MVS says that there is an ideal proportion for every room in a home or office. Also, the length, width and elevation of the building are individually calculated using the ancient Vedic mathematical formulas and requires a level of construction precision that includes a one eighth inch error tolerance.
MVS planning and building is said to take into account the effects of the sun, moon, planets and stars and also using the poles and the equator as reference points. The measurements and proportions are calculated in reference to proportions of the human physiology and the cosmos. This results in building proportions that are in harmony with nature.
One unique feature of a MVS or "Vedic building" is a center space called a 'Brahmasthan', serving as a "silent core" which is "never walked on" and is "lit by a skylight". The Brahmastan is said to act as the "nucleus" or axis point for the structure like the nucleus of a cell or an atom.
Other unique features include a perimeter designation called a 'vastu fence'. This boundary line may consist of shrubs or a metal, stone or wood fence. Another feature is a "small, golden, roof ornament" or cupola, called a 'kalash'.
Three "special ceremonies" performed on "auspicious dates" are recommended by MSV. These include a ground breaking in which is described as digging a precise square hole while facing East, adding organic fertilizer and "sacred water" from India and making statements of goodwill and success for the new construction. A cornerstone laying and moving in ceremony complete the trio of recommended procedures.
