Vastu has a scientific basis, and its principles are derived from the ancient Indian texts like the Vedas and the Upanishads. The principles of Vastu revolve around the concept of energy, and how it flows through space. Vastu aims to create an environment that is conducive to the flow of positive energy and eliminates the negative energy that causes physical, emotional, and mental stress. It is believed that a Vastu-compliant space not only enhances the quality of life but also promotes good health, prosperity, and success.

Vastu takes into account the direction, shape, and size of a building, the placement of doors and windows, the position of rooms, and the use of colors and materials in construction. It is essential to follow Vastu principles right from the time of land selection to the construction of the building. The direction of the plot, the slope, the soil quality, and the presence of water bodies or other natural features are also considered while selecting the land. The construction of the building should also adhere to the principles of Vastu to ensure that the energies of the universe are in harmony with the living space.
