Can you elaborate on identifying the various parts that push against each other? What are these parts? Voices or something more subtle like desires or aversions? As an aside, based on various therapies I’ve worked out my method of emotional acceptance of past events and traumas which has and is helping me to accept and integrate them, but it still feels crude. I catch any strong emotion and then observe it and allow it and accept it. Sometimes it’s tied to a seemingly trivial memory(my mind trick is that the memory is not actually trivial) which I can look at and integrate and accept as well.
