Chris, that is actually just part of the work I do... I would say it is partly about trauma but mostly about feeling a greater sense of wholeness. Soul loss can lead to behaviors that are about trying to fill that void, and a retrieval often clears much of that (or makes it much easier to shift the patterns)... and can get the person feeling flexible about sense of self to raise their self-esteem. Boundaries and presence are good side effects, but I'd say at the core it is about feeling more complete within yourself.
Very interesting ideas about personality, I had not really thought about it much aside from what I already said.
