Would our client benefit from another subconscious channeling at this point to help his problem with mouth ulcers, or is more Protocol work of greater benefit?

Both are still of value because of the problem of the mind’s power. The cellular memory continues to be reinforced by his conscious agonizing and focus on the problem which is hard to avoid given its severity. That is why this is a major chicken and egg problem as this is the perennial dog chasing its tail—as long as there is a tail, the dog will chase, but the dog itself is bringing the tail into view and gets that cycle going. So there is an element of reinforcement via the subconscious that can be benefitted by addressing this very thing through subconscious channeling.
