For an live example of guiding a client through changing a belief listen to this podcast episode https://pathwaytohappiness.com/blog/p...

In it I walk a client through these same steps of identifying the belief that resides beneath a thought, changing perspective, shifting the emotions of fear, and the energy of faith in order to change his belief.
A belief, particularly core beliefs operate in our unconscious. That means that we don't know they are there. It is as if we were hypnotized and behave in ways we don't want to. We wake up after our emotional reaction or unwanted behavior and wonder why we did what we did.

We only see thoughts, emotions, and behaviors that unconscious beliefs produce. The exercises from my Self Mastery Course, and my book MindWorks allow you to become aware of these core beliefs and change the beliefs, emotions, and false sense of identity that form them. This is how you make changes at a core belief level.
