How helpful and representative are cordings to the upper levels of the mind about past life traumas that are launched by the deep subconscious? Does the deep subconscious even know when it is creating a potential path to healing?

It is true that anything discoverable by the conscious self, which does get worked on in a meaningful fashion, can result in a net gain. But what is being generated by the deep subconscious is a quite varied, scattershot, smattering of the issues it surveys and grapples with. Among them will be juicy targets for trauma resolution work, but most of the time it only serves to upset a person and add to their anxiety because, while the conscious self might be able to connect to that cording, it will need the upper subconscious to assist and, at that juncture, it is likely the conscious self will not be in a position to appreciate what it is learning and will thus be a missed opportunity. The key in understanding the dynamic here is that the deep subconscious is not sophisticated, it is not learned, it has a tremendous information processing capability but no prior instruction about what everything means and how to go about any sort of logical analysis and rebalancing of things. What happens for the good is only something instinctive being brought about that helps, to some extent, alleviate a negative input. This happens on a regular basis among all levels of the mind when there is memory recall and then some way of readjusting the memory to neutralize it and, by taking that visualization to heart, it might stick when the memory is reconsolidated, and thus healing a portion of old business albeit likely a small one. But that kind of coincidental relieving of pressures and accumulated negativity is a far cry from having a robust healing program capable of dealing with a mountain-sized backlog of old karmic business all carry from their hundreds of lives when many bad things happened that were not effectively rebalanced. So there is always much more to do than can be done, even with a concerted campaign, at least without divine help, so this signaling by the deep subconscious will not be a natural answer for the healing needs of an individual to clear their karmic backlog.
