Vastu is a cosmic ancient science which is based on five elements of nature and different directions ie East,West,North,South.
Vastu ( or vasthu or vaastu )is one of the most ancient sciences of Indian architecture and is composed of specific rules, regulations and directions, set down by sages of the vedic times. For the modern society it is the highly evolved, comprehensive building philosophy.
According to vastu, a building or premises is a living organism and can be designed in harmonic resonance with the underlying energy structure of the universe. Such a building or premises becomes a generator of coherence, attuning the occupants to the universal laws and increasing health, wealth and spiritual well being.
Ancient scholars are the equivalent of today’s scientists. They saw the world as a unique in which "life-force energy" was the main component.
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.
