Before I joined scn, I had read a couple of non-scn books about past life regression, and really bought into it, so I had no problem with the concept. I had past life recall very early on in auditing and believed in it at the time. However, I can't say that any of it ever made any real difference, other than a passing emotional high.
I would probably be more impressed if there was anything in it that I could have proven objectively, or even without this, if it had made a clear and lasting change in my own personal set of difficulties. It never did, though.
I can also mention that my view of life was a lot more spiritual before scn than after.
You mention phobias; last year, I very suddenly developed a strong fear of escalators and stairs. There had been no accident, no obvious reason. Apart from being terribly impractical, it annoyed the hell out of me. But I really panicked. I do have a wog psychologist in my family who knows CBT, so I asked him for tips, and then I worked hard at it. Within a few days, I had beaten it. People choose their own paths, and to each their own, but I'm glad I wasn't stuck in trying to recall things in session, hoping to eventually find something, when there was such a quick, hands-on approach I could take.
