My client [name withheld] is still getting throat ulcers on a regular basis and wants to know if another subconscious channeling would help. Is this important to do for his making further progress or will it be sufficient to include him when I do group healings with the Protocol?

Both things are true. Any subconscious channeling work will help to reach the end goal, but also it is true that without it, repeated Protocol sessions will continue to help him make progress and he will reach a healed state eventually.
