Hypnosis gives us access to the Subconscious level of Mind. Regression gives us access to the events that are feeding into the problem. The goal of regression hypnotherapy is to get to the root-cause of the problem.
These are the fundamentals of regression-to-cause theory. And that is that in the absence of an organic cause, the cause of the problem lies in the client’s personal history. So, the objective is to find out where the problem got started and resolve it there.
If you can remove the underlying cause, then there’s nothing left to generate the symptoms.
Symptoms are not the problem. Symptoms are symptoms of the problem. They’re what tell you there is a problem. And what the real problem is will be revealed through the process of regressing the client to the causal event.
