Vastu shastra is a traditional Hindu system of architecture which literally translates to science of architecture. These are texts found on the Indian subcontinent that describe principles of design, layout, measurements, ground preparation, space arrangement, and spatial geometry.
Vastu is the science of direction that combines all the five elements of nature and balances them with man and materials. It is all about the interaction of various forms of best effect on a living person. It aims to create a subtle conducive atmosphere in a structure in which we can bring the best in ourselves, thereby paving the way for enhanced health, wealth, prosperity and happiness in an enlightened environment. Like any other science, vaastu is universal, rational, practical and utilitarian. It is not a religion but a science.
The principle laid down in Vastu Shastra were formulated keeping in view, the cosmic influence of the Sun, its light and heat, solar energy, directions 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.
