Don’t need magnets.
It’s often called the “releasing” technique and is taught by several different people under different names.
Just put your hand on your stomach if you need to and bring up the situation/memory/etc that brings up the emotion and related body sensation.
As I know you have the Energy Awakening course, it’s the same method taught by Sammy to release emotions.
Send it love
or
Just accept it
or
Ask it questions
etc.
until it melts away
All just ways of “integrating” that emotion… translated as the body sensation, into Oneness/Love.
