In Sanskrit, Vaastu means to build environment and a surrounding and Shastra means a perfect system or a by-laws. The word Vaastu came from the Vastva, means anything that provides shelter. Vaastu Shastra tells the methods for building any kind of shelter that have congenital environment due to the combined positive effects of the five elements called Panch Mahabhuta. Vaastu Shastra encompasses the techniques to decide directions, placement and positioning of various aspects related to building. If any shelter, be it home, commercial establishment or industrial premise, is built on the guidelines of Vaastu Shastra, if certainly bless the owner with health, wealth, prosperity and happiness.
According to Vastu, (or vaastu or vasthu) there are five basic elements in the whole world. They are the Earth, Water, Air, Fire(Heat & Light) and Sky(Cosmic). Vastu is a science of balancing these elements in the proper proportions for harmony.
Vastu essentially deals with two energy sources the solar energy flux and geomagnetic energy flux. We cannot see energy with our naked eyes but we can realize and see its application in different forms. The aim is to control the flow of these energies by selecting proper direction and alignment and by understanding the directional energy flow one can easily relate north & south to geomagnetic organic flow & East & west are related to solar pranik flow. . Vastu uses these forces of natural energies and aims to restore the balance between the home (the microcosm) and the cosmos (the macrocosm). If there were an imbalance between the directions or the energy flow, the resultant energy would be negative energy, which would then result into environmental aggression, creating disharmony among humans residing at that particular space.
More recently, studies conducted on geopathological stress have shown evidence of the relationship between people’s well being and the natural energies. While negative energy can adversely affect the nervous system, the genetic code and the immune system, positive energy can sustain our well being, enhance our ability to counteract stressful situations and increase our potential to succeed.
