Arnold,
Please look at my website for more information about past life therapy and "life between life" therapy.
Usually, as a matter of course, when doing a past life regression and passing through the moment of death, a client will go into the "LBL" state to some degree. That is where the real processing of the past life is done, and also where one can connect with the Higher Self, the soul consciousness, or whatever you want to call it; that state of consciousness has different names.
The way I do the past life regression therapy is psychologically based. We address specific emotions, thoughts, and physical symptoms--different aspects of the present personality--to access the past life material. This makes the regression relevant to the present life and also has therapeutic value. I don't suggest to a client to go to a particular time period. Other therapists may use that approach, but I don't find that to be as helpful or relevant.
If you are interested in doing a past life regression, please use the contact information on my website. I do screen clients before making an appointment. I want to make sure that you understand what's involved in a session, and I want to determine if past life regression is appropriate for you.
