VASTUSHASTRA, an ancient Hindu practice to construct buildings in harmony with natural forces for well being of humanity, is given in a number of ancient works including Vedas. It is the traditional Indian system of architecture and design of Vedic origin. Vastu means the dwelling of humans and Gods. Vastushastra is a result-oriented science and gives definite and immediate results if applied properly. It defines the proportions and details of building elongation, slopes, water tanks, kitchen, bedrooms, stairs, heights of roofs, entrances, doors, windows, walls etc. Living in harmony with the nature is theme of Vastushastra. Perhaps one of the main reasons why the human beings on earth are unhappy is that they are unable to adopt a habitation which offers them the best out of nature's elements like earth, sun, air and water that govern the course of their lives. Any house built as per Vastu would bring happiness and prosperity to its occupants.
