Vastu is a science of direction that combines all the five elements of nature and balances them with man and materials. It is not a religion but a science. The principles laid down in the vastu Shastra were formulated keeping in view, the influence of sun, its light and heat, solar energy, direction of wind, the moon position, the earth’s magnetic field and the influence of cosmos on our planet. The system is an admixture of science of directions, astronomy and astrology.
