I had a therapist who ended up a Jungian later. He nicknamed a part of me the Samurai. It wasn't an inner voice but a way of doing things. I grew up in a strict military household that did not permit any needs or any signs of vulnerability. So I grew up as a "tough soldier" which in the end was causing me harm so identifying it was a way to notice the times when this kicked in and try to soften it somewhat.

When I switched to another shrink, he didn't really believe in separating out different parts. His general approach is cohesion or integration so naming something as distinct would go against this idea to some extent. Occasionally I will bring up the Samurai and he understands what I mean and agrees with the general idea.

Over time that the Samurai has softened and almost completely dissolved so I still have some of the strength it provided when I need it, but the rigidity of it is no longer there.
