Many people dismiss Vasthu as a waste of time and as a superstition. In reality Vasthu is an architectural science that deals with building houses in accordance with purpose, rules and best practices. While some of its recommendations may seem archaic and downright silly, Vasthu has a logical reason behind each of its principles. For example, Vasthu recommends building houses with thresholds that face either the Northerly or Easterly direction. This is something that many would not even consider, yet history and experience shows that houses constructed with the principles of Vasthu appear more graceful, peaceful and flowing. This can be seen frequently in the buildings of South India.

Vasthu calculates rainfall, wind, sunrise and sunset to identify the ideal way to construct a house. If a house faces north then the effects of harmful UV rays from the sun on the threshold, where members of the house and guests congregate are highly minimized. Similarly an East facing house has the advantage of being graced by the rays of the rising sun which bring life, vitamins and nutrients. Hence Vasthu is not a superstition and pseudoscience. It is rather a clever set of principles put together by our ancestors to bring betterment into our lives.
