Vaastu shastra, which means the science of the built area, is an ancient Indian architectural science. It is the study of the forces of nature and their effect on an individual's immediate environment. This science is perfectly in tune with the natural laws and lays down the rules to create harmonious environs for living by connecting the individual with the cosmic forces surrounding us.
Vaastu Shastra is divided into seven main parts:
Method of soil testing.
Selection of suitable land and finding out its directions.
The division of land into squares.
Method of construction.
Placement of entrance gate.
Knowledge of construction of temples.
Knowledge of construction of palaces.
Vaastu Shastra is based on the laws of gravitational forces, magnetic forces, flow of electric current, flow of wind and water, and takes into account the importance of the sun's rays also known as the solar energy. The proper effect of all these in necessary to keep good health and balance of mind.
Vaastu is an ancient architectural tradition of India based on the Vedas. Vaastu developed its building technology on the fundamental premise that the earth or soil is a living organism out of which other living creatures and organic forms emerge.
Vaastu by tradition is the life force contained within the earth. Vaastu also means living space or dwelling space. Vaastu is the individual site or land identified for a village or neighborhood. Vaastu is also the building enclosure.
Man does not inhabit this earth alone; he inhabits akasham or space. He is linked with his Shakti or energy to other energy form. He is part of a movement, a cycle of life and death, which is known as Kaala (time). Space, Time and Energy are traditionally primed as existing in their free, unlimited state. Vaastu experts have not only devised an order pertaining to the creation of manifested space, but have also ascertained a link between time cycle and the life of a person.
Vaastu is not about magical cures but about the physical, psychological and spiritual order of the built environment and its consonance with the energies of the cosmic universe.
The science of Vaastu revolves around the affect of the 5 elements (Panchbhuutas), on the human body.
