Is it safe for the practitioner who inquired about this, to do Lightworker Healing Protocol sessions requesting divine healing for Lucifer and his direct reports in the hierarchy of dark spirit meddlers?

This is safe to do, the only caveat being it is best done in a calm state of mind when she is feeling relaxed and confident and not rushed and under stress. This is not meant to undermine what we are saying in any respect, simply prudence and good general practice. You would not want to participate in a playoff game in sports when not feeling your best or going about it half‑heartedly, being distracted by other concerns, but totally focused and intent on the matter at hand—that is all we are saying. This she can do quite handily as she is a seasoned practitioner and intuitive of great talent and knows how to govern her energy well. She will have no problems doing so.
