my friend does Reiki massage and everybody finds it very relaxing but when she tried to help undo my physical knots she couldn't.

she said it was my fault, because i did not "believe" enough.

i do not really believe i n radio, because i do not understand how electromagnetic lines can be bent when they are always sposed to travel in a straight line; but i still enjoy the radio, it works for me, but this massage doesn't.

what has belief got to do with it?
