Ok. I trained i Philipines. There where many psychos who could dovery interesting things with theirmind. But they all believed in go and jesus. They didnt really understand whats gong on. Fact is, they believed they could do this, and there werent any blockades which held them up to do this things. But the most important thing i learned was, like granmasterchen said, they learned it by hard as they were children. Many times i saw little boys, about 2 or 3 years, who were jumping from 3 meter high trees and without hurting themselves. Then the older people said me, that when you let children do something, they dont need to be afraid.
When you try to jump from a 3 meter high tree, you just thinking about how not to get hurt, cause your mother always said to let it be, cause you getting hurt. Then your mother made a barrier, whichcant be removed. i think believing in his own doings can help. in phillipines they belive, that nothing can get wrong, then god is always helping...
