This technique erases any past life blockages that are effecting you in the present time. With Past life Assimilation you tap into Past Life memories consciously healing any trauma associated from that experience. You will also have an understanding of how this has affected you in this lifetime. You may find changes within yourself as your personality adapts to accommodate a less limited way of thinking that had been carried over from the Past Life.
This is not the same as hypnosis because you are accessing the Past Life memory, it is like the difference between watching a movie and being part of the play. When you do this you can own the event and change your feelings towards it.
The Past Life that will come up is the one that is currently blocking your life at this time.
