Lasar zentrum Research Institute Germany and ITMO University Russia has done research on the energy inside the pyramids, They got many tremendous results working on optics and electro magnetic waves inside pyramids.

Even a layman can easily experiment on the energy of the pyramid if you keep one fruit inside the pyramid and one fruit outside

After three to four days you will see that the fruit kept outside will start spoiling while the fruit kept in the pyramid remains intact.

Two things are very important in the pyramid, first one of the sides of its base should be exactly in the north-south direction. Second, The angle of the pyramid should be 51⁰ 51′ 51″ . The energy center of the pyramid is at 2/3 height from its highest point, so keeping that part of the body at the height of the chakra which is blocked, that chakra is sure to be correct.

Try to meditate sitting alone in the pyramid, due to different energy levels of many people, there is a possibility of disturbance in your energy.
