Geographical situation of an area affects the nature thus the vastu for every place changes. We see that some countries are much advanced, developed and prosperous while others are much backward.

Apart from the geographical conditions and different nations, if we take examples within our country, you will be surprised to see. Have you ever thought that why tajmahal is so famous that it has become the 7th wonder of the earth and why exactly similar structure called"chandbibi ka makbara" situated in Aurangabad is not yet known to the people. Why is so that the Tirupati balaji is world famous and other temples situated in the same regions are still waiting for the pilgrims to come…. This is all vastu , they are famous because they are made according to vastu.

Thus to achieve the happiness, peace and prosperity, one must follow the principles of vastu.
