A practitioner asks if it is possible to treat the collective unconscious as a client with the Lightworker Healing Protocol? Wouldn’t that violate free will without going to the higher self of each human to ask permission?

Your question provides the answer, as that is the stumbling block. The beauty of the Lightworker Healing Protocol is that it is working through us, not your energy, and we always obtain permission from each individual’s higher self for each step in the Protocol to be applied. So while you could do the same, as a channeler able to reach higher selves, it would be a quite burdensome complication and is unnecessary as it is an automatic built-in feature of the Protocol. Because we are working on each human and in every case we consult with each individual’s higher self for the permissions needed, your execution of the Protocol will accomplish the very thing this practitioner is wanting to have happen, so it is simply not being appreciated that there is very much healing for this aspect of influence on humanity already ongoing with the Protocol work.
