The biggest Proof of vaastushastra can be found during the time of Ramayan and Mahabharat. Even in the cities of Mohanjodaro and Harappa the application of vaastushastra can be seen. Since the science goes far back to the times of Lord Rama and Lord Krishna there are many interesting mythological stories concerning the origin of Vaastupurush (the deity).
 
If you consider it a mythological fact then here are the most unbelievable examples that Vastu is a science and one must follow it wholeheartedly.
 
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. For e.g.

• Japan, existence of deep water in North and the East is considered most auspicious according to vastu shastra. The eastern side of Japan is widely spread and open. Thus Japan gets full benefit of the rays of the sun. This is why Japan is rich and prosperous. There is sea in Southeast and south of Japan, which is a place for Fire, this is why it suffered the attack of atom bombs explosion and earthquake.

• If we take Africa as a continent, we all know the northeastern corner of this continent is interjected. Northwest portion is projected, southeast and south have unlimited water, these all conditions are inauspicious according to vastu, that’s why African countries are backward, uneducated, poor. But on the contrary, in the north of this continent, there exists Mediterranean Sea, which is favorable according to vastu. In the eastern part, river Nile flows and that’s why civilization developed in Egypt and now Egypt got name and honour for its world famous pyramids.

• Why to go far, lets discuss our own INDIA, we know we have the Himalayas in the North and Northeast side of our country which is against vastu, thus there is lot of poverty in our country. There is water in Southwest and southeast side of our nation, thus we have to face the attacks of foreign empires. One thing that makes India famous is that we have our slope towards east, which is a very favourable and auspicious sign.

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.
 
Vaastu is an empirical science. Over the years, based on the knowledge in the Vedas, repeated studies on a number of buildings, offices, temples, houses, apartments have shown a positive correlation between the application of Vaastu principles and success. It can be extensively applied to various edifices natural and man made land masses, temples, factories, homes, office buildings and corporate headquarters.
 
Mumbai again has water in the North East and the Atomic Power Plant (Agni) in the South East thus according to Vaasthu principles and the most powerful, prosperous place in India.
 
The location and construction of the famous Balaji Temple, the most prosperous in India, are all according to Vaastu: Water tank in the Northeast, Kitchen in Southeast, and the Lord in Southwest facing East and so on. Studies conducted on cities like New York, London, Singapore, Hong Kong etc have shown they are according Vaastu principles.
 
The most famous prosperous industrial houses have also been studied; The Tata head quarters in Mumbai, Akbarallys the most successful retail store in India, factories of FACOR a highly successful industry in A.P. and many others have been found to be according to Vaastu.
