The human mind can do amazing things that we haven't even begun to comprehend yet. One can suppress their immune system and become ill just by being depressed. Well what if we could use this mind over matter to help us cure any number of diseases in ourselves.
Now lets take this to the extreame. What if you believed something so strongly and completely that you could actually use your muscles to convulse and
make openings in your flesh. Hense stigmatas. Since we don't consciously know how to do this it would appear to be supernatural. How else do
you explain why stigmatas are more often then not in the wrong place. The popular images that we have come to know of Christ on the cross show his
hands have the nails through them and this is often where people receive the stigmata, but that is wrong! Jesus could not have received them in his
hands because they would have torn right through. If he was nailed to a cross, he would have had to been nailed through the arms because of the bone
Just an idea.
