What Are the Most Powerful Techniques in Cognitive Behavior Therapy?

The most important concept, I touched on earlier when I said it's not things upstairs, but rather opinions about them. One is a concept and the other one is that is actually a technique, but it's a very subtle technique. So there are lots of techniques that the stoics bequeath to us. But as a therapist, I would say it's the distinction between theory and practice isn't as sharp as people might think.
