Two people can walk over the same coals at the same pace, and one will burn their feet while the other won't. I am not saying it is paranormal or supernatural- I am saying that it has to do with the inner state, and that the mind has a profound affect on the body. Also, it is well known by anyone who has walked around in a room while listening to a radio that their are electro-magnetic flows moving around us all the time. This is explained partly by variations in the earths magnetic field due to flows of magma in the earths core, and the interaction of the flows of solar radiation.
The nervous system, most prominently the cluster of neurons called the brain, functions through electrical impulses. Electrical conduction generates an electro-magnetic field, which in turn can be picked up by radio receivers. No one has been able yet to measure effects of electromagnetic activity on the behavior of individual neurons. However, thought forms may be able to have independent coherence, or sentience, on these frequencies. This would explain the descriptions in nearly every culture around the world of faeries (Ireland), elves(Germany), duendes(Spain and Latin America), kamis (Japan), jinn(Middle East). This can also effectively explain the global phenomena of possession, and the cases of the possessed speaking in languages they could not ordinarily speak.
Have fun with this one, materialists...
Guess you never watch mythbusters then. Walking over hot coals as nothing at all to do with "the inner state" ROFL
