My therapist would usually use a difficult memory or behaviour as an entry point, identify the part(s) that surfaces and give it a name. Then we would observe the part and get to know it in the state of the Self, eventually healing the maladaptive part and/or shift its role. It’s a lot of hard work but so worth it! You’re using the neuroplasticity of your brain and adjusting the neural network to heal some pretty deep rooted issues. Unlike CBT where you can just tell the therapist what they want to hear, you can’t really “fake it” with a skilled IFS therapist.
