A.H. Almaas identifies 18 "I-states" or "ego-states" associated with healing narcissistic wounds. This is the kind of work we need to do in order to take care of the shadow aspects, projected outward, that result in, for example, authoritarian political characters appearing on the global scene in leadership positions. We can use "voice dialogue" to enact whichever of these I-states seem most relevant to our experience at the moment, giving us a kind of map of the territory and a way to navigate it towards wholeness.
Here are the 18 I-states: "fake self"; "hard self"; "wounded self"; Betrayed self; raging self; pointless self; lost self; shameful self; rejected self; spacious self; self-active self; depressed self; helpless self; trusting self; ideal self; loving self; essential self or unique self.
In voice dialogue what we do is "speak" TO that self and then AS that self, which helps us to fully accept it. Once fully accepted, a difficult sub-personality will usually "let go" on it's own. With self-states that are "true" and healthy, we don't need to let go of them. “That which is true can never be lost”.
