ANSWER: Vastushastra is a science - it has nothing to do with religion. It is true that over the years. Vastushastra has imbibed religious overtones, but that does not seem to have been the original idea. The religious implications were probably iculcated by the proponents of the science, when they realised that the society of that times was a God fearing one, which would not accept norms that seemed like rituals performed to appease the God.
