People who get triggered are going to get triggered again. Events in daily life can act as reminders of unresolved, painful events from the past. When this happens, the underlying Pain Package gets triggered, which reinforces the whole problem. We call this the Compounding Effect.
The Compounding Effect is the reason problems tend to get worse over time. It's because each time the person gets triggered, the problem gets stronger. So, over time, small problems can grow into Big Problems.
It's just how the Mind works.
The Subconscious Mind has a real talent for making mountains out of mole hills. And this is what we find in regression hypnosis sessions. Often, the underlying problem is no big deal. But the client doesn't know this.
Once this is brought to conscious awareness, the client no longer has to suffer with the symptoms, any longer. When that happens, the whole problem can let go of. Regression to cause is what makes this possible.
