It has been proved by research of Dr. Patrick Flanagan, USA that energy level of Shree Yantra having accurate geometry is 70 times more than equivalent Pyramidal Structure.
For example, energy of large (M-108mm) Shree Yantra is 70 times more than the energy of Pyramid of same size. Means energy of Large (M-108mm) Shree Yantra is equivalent to energy of 7.5 meter (25 ft.) tall Pyramid.
