I think as skies said, resistance is therapy. It's usually unconscious though, and it provides important information to a T about where the difficulties reside and how they came to be. I think it's unfortunate that it's called "resistance" because it has nothing to do usually with a willful refusal to cooperate in therapy. It's more an unconscious pattern of defenses to either self-protect or to order the world to fit the perceptions you've developed over a lifetime.
