Oneself (including parts that one is not aware of yet) can be seen as having different Parts with different aims.
Some of these parts can implement limitations, so it is worth working with them to cease their implementation of limitations, which can be persistent for various reasons.
It is possible to talk to the Part, find out the reason it is insisting on implementing its limitations, and finding a way for it to do something better instead.
For example, if a Part won’t let non-ideals be erased because it considers that one deserves those non-ideals, due to negative things one has done in the past, one can explain to that part that holding those links to negative things in the past, makes similar negatives more likely to continue to be done, and to improve one’s condition to where one is less likely to do such negatives, requires erasing relevant non-ideals. When that part understands this, it will allow that are to be processed effectively.
Some parts might insist on implementing limitations because a big being told them to at some point in time. So, one can erase their stored reality on that “big being” until it no longer exists for them, then they will have no reason to continue implementing those limitations and they can be processed effectively.
