What is the reason for our client’s persistent sense she has an attacker in her mind even though we did a clearing for her with the Protocol?

As you saw intuitively, this is a residue of her mind manipulation courtesy of the spirit meddler attackers you removed successfully. They have indeed established a mind loop of self-tormenting so they can make her miserable and keep her worried and not have to do anything actively themselves. This will fade in time if she can learn to ignore it. If you continue to do healing requests on her behalf, this will be of assistance, but as with so many others, it may take a while to have relief. This is most unfortunate but it is simply a legacy of their handiwork. It is no different than a human attacker coming in with a knife, cutting tendons, and muscles, and perhaps poking out an eye. Even though police are summoned and the attacker pulled away before killing their victim, the person harmed by the knife attack may have a long period of suffering and healing in store for them to begin to feel normal, and there may in fact be long-term alteration that would require very intensive healing efforts to undo. This is true of mind attacks as well. The ability of divine realm to heal things exceeds that of human, but we must stay within the realm of what the humans themselves consider to be possible, and when there are doubts and fears, that will limit us and limit our reach. If she maintains her faith and especially if she adds to your work with prayers of her own, for own healing and rescue, this will help us greatly to continue to undo the harm that has been done and she will be able to get back on her feet and move beyond this. If she gives in to fear, not only will these thoughts and sensations persist but she will likely attract new darkness to her as well. We say this not to instill greater fear, but to emphasize her personal responsibility in what happens in the future. She must do her part here to stand strong and not give in to weakness and to fear. That is playing their game and it will help them win. She is truly a fine person and a very spiritual being and does not deserve this plight, but she is in charge of her experience so we are bound by the rules to only do for her what she will allow and is ready for. And again, we do not wish to assign any blame to her. That is not what we mean by all this. She did not ask to be attacked, but now that it has happened, she must take the responsibility for her well-being once again, even though she has divine help at her side. We will do all we can in partnership to right this wrong.
