I've understand what you said, but my father intended an other kind of brainwashing.I'm going to explain it: he says the people who theach you the PR method makes you think that PR works, so when you're convinced that something works(in this case PR)...then it really works.
He says is not a "scientific" method to learn, but something create to makes money.
He says that everiyhing you're loking for you'll find inside your self...
