Why does it work?
Instead of using the analytical mind (also known as "Beta" brain frequency range), which obviously couldn't solve your issue if you are still struggling with it, you will use the creative, intuitive mind, in the "Alpha" brain frequency spectrum
Your brain doesn't react to reality but to the inputs of your senses and emotions, in repetitive patterns. You can re-program your brain responses by inducing new patterns associated with desired emotions/sensations/outcomes
The metaphorical language is read differently by your brain, therefore it's used to unlock different solutions
When was the last time you shared your deep fears, discomforts, tensions, ill-being or confusion with someone? Speaking is liberating. Liberating is transforming.
