Logan stones are heavy stones that are located around the world in the same way as menhirs, dolmens and other megalithic structures. Their speciality is the fact that they aren't in contact with the subsoil by a surface, but only by a point. Some of them are balanced in a way that wind swings them. In other cases, rocks are placed onto a few smaller stones. A similar placing could also be found with dolmens, where a top desk is placed on top points of stones. The placing onto small surfaces isn't coincidental but has its foundation. In my previous articles on www.miroslavprovod.com, where I'm writing about properties of cosmic energy, I'm stating the conditions under which the flow of energy occurs. Matter could gain energy, it could be in a balanced state or it could be losing energy. The construction of Logan stones wasn't coincidental, the energetic loses were higher than the gains in their locations and therefore it was necessary to minimize loses in a way that the contact surface of the rock with the subsoil was minimized. The same technology was used by the constructors of mounds and other clay ramparts, who separated the matter of the rampart from the subsoil by organic matter. In the case of Logan stones the matter of the rock is separated from the subsoil mainly by an air gap. This could easily be understood, but it's much more complicated in the case of Logan stones that are swung by the wind. Balancing of such a heavy rock was much labored and this must have had a significant reason. I was looking for the answer by doing experiments. I connected a sphere made from red granite that weighed 6 kilograms to a tree branch by a two meters long string and swung it for fifteen minutes. I was surprised when I then identified the energetic gain of the granite sphere - I measured its aura having two meters in radius. I repeated the same experiment a number of times in other places always with the same result. This proves that Logan stones gain further energy by the swinging motion. This and previous experiments show that the motion of matter could also be a source of cosmic energy in other cases. It will be interesting to invigorate this phenomenon in other cases. I think that the time to correct our present opinion about the technical level of prehistoric civilizations has come. Hundreds of thousands of accumulators of cosmic energy (menhirs, dolmens, Logan stones, clay ramparts and other megalithic constructions) located around the world hint that they couldn't have been built by primitive peoples. On the contraries, we aren't able to understand the purpose of megalithic constructions, which is highlighting the forwardness of early cultures. If we think about it in a way that the direction of their technical development could have been different from ours it will induce an increased interest in further research in this field.
