Science of Vastu

I have been asked this a million times, How can few walls in our house show our past and future?

I will now start with What is Vasty Shastra and explain how it reflects our future.

Vastu Shastra is an ancient Indian science. A Vastu dosha in Vijay Nagri’s Maya Sabha caused Mahabharat between the Kauravs and Pandavas and their entire generation is said to almost vanish after that. FYI the dosha in Maya Sabha was a water trench in the center of the premises, As per Vastu, any water body in the center of the premises is a major Vastu dosha.Now the main question:

What is Vastu Shastra?

It is a meta physical science that balances 8 directions, 5 elements along with the gravitational force, electromagnetic force of the earth, and the cosmic force emitting from the atmosphere to balance with human life for progress, progeny, finances, physical and mental health, progeny, stability, leadership, etc.

FYI Vastu literally means the " science dealing with building" Ancient References of Vastu Shastra can be found in the following Books:
Matsya Puran, Agni Puran, Ramayan, Mahabharat, Vedas, Bhagwad Gita etc.
Ancients Saints of Vastu Shastra are:
Indra, Garga, Vashistha, Kashyap, Vishwakarma, Vasudev, Atri, etc
Did u know even “Ram Setu” built by Lord Ram was built as per Vastu shastra?Chapter “Kishkindha Kand” in Ramayan shows the cave where Lord Ram rested also was as per the Vastu principles. Many such examples can be traced in our shastras and purans. Also, not only the direction but also the slopes inside the plot, the junctions around the plot, the shape, the approach road, the hospital, railway station, crematorium, mall, etc around is also taken into consideration while analyzing the Vastu of any given plot whether commercial or residential. Now it's for you to decide whether such age-old science is capable to predict your future or not.
