'Vas' means 'to dwell' or 'to occupy'. Vasthu means 'dwelling place.' Vasthu Shastra is the set of guidelines prescribed by the Rishis or learned by men of ancient India for planning and constructing our dwelling places which range from our homes, cities, states, countries and eventually extend to our planet and the universe!
Nature consists of Panchabhutam, the five elements - Akasham or Sky, Vaayu or Air, Agni or Fire, Bhumi or Earth and Jalam or Water
The shastras or the ancient Indian texts on science tell us that cosmic energy has a specific influence on living beings.
Five elements reside in nature in specific proportions. Vasthu Shastra involves the alignment of these five basic elements according to the law of nature. The effects of these five elements have to be studied to appreciate the science of vasthu in its pure form and also to pacify skeptics who question the efficiency and validity of vasthu shastra.
Plants and animals live in perfect harmony with nature. But we human beings, the superior beings that inhabit the earth, have forgotten how to keep peace with our surroundings. If we can modify our homes to harness the energy of the cosmos in such a way that our homes are in complete harmony with our bodies it can help us to succeed in all our endeavors. Due to the magnetic properties of the earth, the needle of a compass always points to the north. Since vasthu is based on the permanent property of the earth namely inclination towards the north, the effect of vasthu is universal. Which means the effect of vasthu does not merely extend to the people of India or to the followers of Hinduism!
The Vasthusasthram has developed over generations as a result of observations of the influence of the SUN and the MAGNETIC fields on earth and living bodies, mentally and physically.
For any problems that you may be having with your health, mental and body peace, it is recommended that you construct buildings "as per the principals of Vasthusasthra - THE LAW OF NATURE
We have to study the level, shape, and size of land before starting any construction. The shape of a land may be changed by adding or deducting parts or corners. We can also provide boundaries to separate the compound to suit Vasthu Sasthram. A land may be square or rectangle with all corners, Right angle is good for construction. A plot that slopes to the north or east or northeast is good for any purpose. In a plot having a way on its east and north and slopes to the east or north is considered very good for construction or for business.
Before undertaking any construction of building you have to think of your financial position and requirements and consult an experienced engineer having a thorough knowledge of the preliminaries of Vasthu. While planning your home, remember to position your master bedroom in the southwest, sleeping with your head towards the south or east. Businessmen may sleep in the southeast or northwest bedroom. Our head has a magnetic power, and has to be placed opposite to the north i.e. place your head towards the south for a sound sleep.
The water tank should be positioned in the southwest / south / west and never the northeast. An underground tank or well in the northeast is considered good.
In remodeling any existing house, you must consult a Vasthu expert. Prabhakara Menon says that he has come across many cases where people complain of financial and other problems after the marriage of a son or daughter. This, he says, is due to the remodeling or rearranging of rooms or a change in position of doors or windows in connection with the marriage.
