Vastu is a science that provides a set of principles for the construction, layout and interior design of houses, temples and even whole cities. Vastu works to establish harmony between body, mind and universe by creating living spaces that are similarly attuned with the cosmic balance and are orientated according to the movement of the sun and moon, the electromagnetic field of the earth, the five elements and the astrological influence of the planets. When alignment is achieved, the living space echoes the basic structure of the universe, and prana (the energy sustaining all living beings) flows freely through the living space, bringing health, happiness, peace and well-being to its inhabitants. Vastu originated over 10,000 - 12,000 years ago from the ancient sacred Hindu texts known collectively as the Vedas.
