Are the beliefs held by the conscious mind in a separate compartment from cellular memory, or the upper subconscious? Can belief replacement for the conscious self be done by Creator directly, during sleep, so as to avoid having to use an exploratory interchange to uncover what needs replacement?

You are realizing, as you ponder your own question and await our response, that cellular consciousness, you rightly describe as the "Body Mind," includes cellular consciousness of the brain itself, and it is the latter which is the repository of the most recently needed and most critically important memories and beliefs shaping the conscious awareness and providing the framework for its day-to-day experience. So the need to deal with deeply entrenched negative beliefs, that can be articulated readily by the conscious self, is to get into that compartment of cellular memory of the brain and do what is needed to rebalance things and replace the negative beliefs that over time have corrupted thinking and hold a person in their grip because people, in effect, become their beliefs and are limited by what they allow to happen.
