In ancient times the human habitats were generally constructed according to the rules of Vastu Shastra and people lived happily. In those days the members of a joint family used to be content, prosperous and happy. But, today, despite the families being small, peace and happiness remains a far cry. As times advanced, we started ignoring our old culture and tradition. The rules of Vastu Shastra too were ignored. No wonder the people experienced all kinds of troubles. You will be surprised to note that even today the residents of South India follow the rules of the Vastu shastra and are more peaceful and materialistically and economically more prosperous than North India.
