I came across an interesting article by holistic practitioner Mary Schneider about the power of resonance.
As explained in the article, we all resonate to past memories or emotions. The example used in the article is how people that resonate with failure usually stems from childhood. Resonance can dictate your response to events. It can explain our reservation to issues or the actions we decide to make.
So I guess the goal to avoid negative resonance is to acknowledge those negative images or memories and reconstruct your behavior and actions.
