Vastu can be integrated as science based on energy emanating from various sources. Energy pervades nature. Our life depends on it. Energy rules every form of life on earth. This energy can be either positive or negative. Incorrect vastu creates negative energy.
Vastu corrections can be done by neutralising the negative energy by strong positive energy radiating devices like energised pyramids and Energy cards. 'Pyramid' means Energy Nucleus which are so powerful, that it cannot be changed by any Energy interaction. That's how Pyramids of Egypt can keep dead body cells free from decay for thousands of years whereas it is common experience that human body and all life forms begin to decay within a few hours of death.
