Our Ancestors, Rishi Munis & Gurus have known the importance of all the five Elements (Pancha Maha Bhutas). They knew their special characteristics to enhance lives since several millennia. Several factors were considered when laying down the principles of this ancient science namely, magnetic field, gravitational field etc. of Earth, the galaxy in the sky, the directions and velocity of the winds, light and heat of the SUN including the effects of its Ultra-Violet and Infra-Red rays, the volume and intensity of rainfall etc.
We often overlook the principles of this ancient science when carrying out constructions according to our modern day requirements. These aversions take a toll in the long run, non-development of business, people falling sick in the family or constant psychological stress can also be because of the Vastu defects in your home or office.
