Vastu Shastra, an ancient Indian science for designing and building, unifies science, art, astronomy and astrology. The goal of Vastu Shastra is to restore the balance between buildings and the universe so as to make the lives of the inmates better.
Vastu is not a religion it's a science of setting the things correctly and balances the five elements that is Earth, fire, water, space, and air to have the maximum benefit out of life.
