Jung's Self, in my understanding, is a process of integration that builds the Self and not a journey toward some pre-existing essence. What does exist is the bag of parts (biology, personal history, culture) that need to be integrated the best we can. I've always found it ironic that folks will try to disengage to 'find themselves' when, in my opinion, that's precisely the wrong thing to do. Time out for reflection, sure. Hole up in a cave...well, I'm not so sure.
The trippy part of Jung comes in when you work through some of the personal stuff and come up against the fracture lines of species and culture that aren't amenable to being fixed but can be worked with in art, imagery, etc.
You're a Red Book, fan, right?
Anyway, a good Jungian should work in dialog with your dreams and reflections (& visions) to find the excluded that wants in and look for clues to integration. I don't like therapies that start with a more specific endpoint in mind.
