According to Indian mythology, Vastu is an Asur (Demon) who prayed to Bramhadev and got boons. This, in turn, spurred an insatiable hunger in him. His power grew to such an extent that he attacked the Devas (Gods) in an attempt to consume their energies. The Devas then asked Bramhadev to help them get rid of this peril. Bramhadev asked the Devas to wage a war with Vastu. During the fight, Vastu was pushed back to Earth and he fell flat on his back with this legs pointing towards Nirrtikon and his head to the Eshankon. Bramhadev then asked the Gods to jump and sit on each organ of Vastu as this will be the only way he can be killed. Bramhadev himself sat on the middle of Vastu, and defeated and killed Vastu.
It is said that ‘The Vastupurusan’ still lies in the same position with his hands resting on his chest. The formation in which the Devas sat on Vastu was used to draft a grid diagram, which helps Vastu experts to decide favourable directions in a dwelling.
Even after thousands of years since its establishment, this science of direction remains to be very popular with people and many housing firms like Tata Housing adhere to it while designing their projects.
Vastu Shastra has been a part of the Indian culture for thousands of years. Even today people consult Vastu experts before buying a new property. Vastu Shastra has its origin in Sthapatya Veda which is a part of Atharva Veda. Vastu Shastra has also been mentioned in our ancient scriptures like the Mahabharata and the Ramayana. The architecture of the city of Ayodhya bears a resemblance to the plans mentioned in the Indian architectural text Manasara. Setu bridge built by Lord Ram was based on Vastu principles. The excavations at Harappa and Mohenjo-Daro also indicate that Vastu Shastra had an influence on the Indus Valley Civilization.
RAMAYANA refrence to vastu shastra have been found in the great Indian epic “Ramayana” also The construction of this holy city Ayodhya,the capitalof Lord Rama shared a similar with the plans written in the great architecturral text’Manasara’even the Ramsetu of Ramayan was based on Vastu principrls.
Mahabharat The Mahabharata is regarded as the biggest and one of the most popular epics of ancient india. it has been said that indraprastha, the city that had been built for the Pandavas, had most houses constructed using this science. Thaehouse that has been constructed in those cities stood tall and looked majestic. The houses had been kept devoid of obstruction and the compounds had high walls with uniform height.the door were decorated with metal ornaments. Even the “Maya Sabha” of the Mahabharata was built according to the acient principels of Vastu Shastra. it is belived that it was built as per Vastu Shastra by the great sculpture called “Mayan” also known as Mayasur(arcetect of asurash) on recomandetaion of Lord sree krishna.maya sabha was square in shape.
Mohenjo-Daro and Harappa Excavations in the ancient cultures at Mohenjo-Daro and Harappa also indicate the influence of Vastu on the Indus Valley Civilization, which show some specific following in construction and planning. They followed certain basic rules in these culture and very much similar and comparable with the Vastu Shastra of Indian origin.
