Vastu shastra is a system of architecture and design, which seeks to harmonize the individual with the surrounding environment. It is based on the belief that the laws of nature, such as the influence of the five elements (earth, water, fire, air, and space), can affect the well-being and fortune of the residents of a building. Vastu shastra is often used in the design and construction of homes, temples, and other buildings in India. It is also increasingly being used by architects and builders in other parts of the world.
