It's like a computer virus, causing mayhem, but running silently in the background. Your laptop isn't behaving properly. And you don't know why. When you do know, the virus can be treated and everything returns to normal.
It's the same with your mind.
You need to reach in and deal with the faulty program in your subconscious. It's causing havoc. But you're not going to destroy it. No. You are going to overwrite it with something new, something positive, something exciting. When you do, your behaviour will change. No more fears. No more phobias. No more addictions.
All this can happen very fast - often in a single session.
