It’s the natural state of the mind to have parts—they are not the product of trauma or of internalizing external voices or energies. It’s just the way we’re built, and that’s good because all of our parts have valuable qualities and resources to give to us. Thus, the angry part isn’t a bundle of anger. If you listen to it with an open mind, you’ll hear it has a lot to be angry about, but it also has fear and sadness and is just trying its best to keep you safe by being angry. Remember that parts have different desires, ages, emotions, and opinions, so they’re like little inner people, and because most are quite young, they’re more like inner children.
