The technique is always “powerful” and quite often is also “secret”, giving us, “the secret powerful technique.”
It isn’t of course. Steam locomotives are “powerful”; Jet engines are “powerful”; a Barrett M82 is pretty powerful too.
But getting a person to shift a picture or two around inside their head or to recite a poxy affirmation is not “powerful.”
Really, it isn’t.
I cannot help but get the feeling that the desperate need to feel that their techniques are “powerful” and can cause harm as well as good, reflects the therapists need to feel and be important.
I wonder if the word powerful and its synonyms were made unavailable, how different the descriptions might be.
