Vaastu – literally means the energy of a building or an open space.

Shastra – Science.

Thus, Vaastu Shastra is the science of harnessing the energy of buildings such as residential houses, temples, schools, places of business, open spaces, pieces of land or even entire towns.

Vaastu Shastra helps in reading the characteristics of houses/plots and explains the effects of the same to the owners/occupants. Since this science is based on the laws of nature, its theories offer us a way of understanding the relationship between humans and their natural environment.
