Introduction
The four basic sciences in Indian culture via Ayurveda, Yoga, Jyotisham and Vasthu-Shastra explain and relate all the facts and phenomena related to the human mind, body and intelligence. These sciences are interrelated and interdependent and have great beneficial influence over life on earth if they are implemented according to the principles.

We live in, and are surrounded by, various types of energy fields, which operate freely in open space. When we built a house or building without measurement and principles, the equilibrium is affected. Vasthu helps in designed the structure to ensure that a harmonious flow of energy is present in the building and equilibrium maintained.

Vasthu considered the interplay of various forces of nature involving the five elements of earth, water, wind, fire and ether and strives to maintain equilibrium as these elements influence, guide and change the living styles of not only human beings but also every living being on earth. Thus, they influence our deeds, luck, behaviour and other basics of life.

What is Vasthu?
An ancient Indian science of architecture, Vasthu, helps in making a congenial setting or a place to live and work in a most scientific way taking advantage of the benefits bestowed by nature, its elements and energy fields for enhanced wealth, health and prosperity.

This science deals about how to construct merit-full houses, temples, business centres etc and is purely astrological science based on the happenings of cosmic rays illuminated by nine major planets of the globe. 
The merits and demerits of the structure fully based on the Vasthu Science in connection with creation of the built-up body. The Vasthu science deals about the measurement details, shape details, nature of earth in construction of buildings in order to strengthen the health of the structure.

'Vasthu' - 'A Place of Dwelling'
The Sanskrit word 'Vasthu' means 'dwelling place' and it is derived from the root verb 'Vas' that means to 'dwell'. It is the mystic study of designing & positioning of architectural structures.

Vasthu finds its references in Vedic knowledge and has come down to us through these years. It considers the five elements - Fire, Water, Air, Earth and Ether - as forces, which originate from a single source but have different characteristics. We are born out of them, we grow with them, we live in them, we are surrounded by them and we go back to them. So why not channelise them during 'life here'? Vasthu helps us utilize this energy to make our lives comfortable.

Be it a home or office, factory or a commercial block, Vasthu shastra is known to reward the follower the benefits and protection from ill effect in life-be it economic, emotional or spiritual. Like any other science, Vasthu is considered rational (based on cause and effect) practical, normative (codified and governed by principle), utilitarian and universal.
