This is effective in the hands of most practitioners to allow connecting to past life experiences and have a revisiting, so to speak. Eliminating emotional disarray coming from the awareness in a deep part of the mind that one is at risk from past lifetime experiences that were highly traumatic can be helpful. That is not the same as what is reached through this hypnotic process. Even though a deep trance state is achieved, it will not reach the deepest levels of the subconscious. As we have explained to you, the deep subconscious is truly disconnected and beyond the reach of the conscious self, even via the upper reaches of the subconscious accessible through hypnotic trance.
To the extent that a given client can connect to some past life material, relevant traumas will emerge and be accessible. This can have a therapeutic benefit in some cases through the realization it is truly past and the conscious self is not truly concerned nor vulnerable to the realities of the past. In some cases, there will be an alleviation of physical symptoms, but for most clients this will be a transient benefit at best. There will be an emotional sigh of relief from having the exploration done that seems to fit their situation so well and with the expectation things will ease now through understanding their origin. That can become a self-fulfilling prophecy in some cases and this is what is leading to the success stories as much as anything.
There can be more accomplished with the coupling of an energetic healing to the ability to access the deep past. That is what is done with Holographic Memory Resolution. So her process is not superior to HMR, other than allowing a greater percentage of clients to access the past life material, but that greater access lacks the superior imagery technique of HMR to formalize a healing strategy through guided imagery and the utilization of an energetic healing process through Color Replacement, so it is an incomplete tool in that regard. There would be an advantage in a blending of the techniques as you have done using subconscious channeling with HMR. The latter is still far superior to what can be achieved with Quantum Healing Hypnosis Technique.
