Vastu Sastra is ancient knowledge of creating a positive physical environment. It seeks to harmonize the layout and design of an environment with the planetary positions and natural elements influencing that location. Vastu is considered so important to the success and well-being of any environment and the people living or working there, that it is treated as its own science in India.
People in the ancient world understood the relationship between energy and our physical environments. They knew that the placement and design of a home, temple or office building directly influenced the health and well-being of the place and its occupants.
They knew that the doors, windows, room placement and decorations really do matter. Every constructional and furnishing detail contributes to money flowing in or out, peace and harmony or tension and anxiety filling the hallways, health and happiness or illness and restlessness affecting the inhabitants.
To maximize positive energies and minimize or avoid these ill effects, it is useful to follow the guidelines of Vastu.
