What can we tell this person about his spirit attacker?

This possessing spirit is being stubborn, but we are working on him and we see that this will be successful. It will take some time yet. So it is important to do your best to withstand the onslaught. It will help to know this is not your fault or because of you. You do not deserve for this to happen, and you are a stronger and better being in every respect. This is a spirit who is truly lost and being used as a tool to cause you misery. That, too, is an evil origin in the sense of depravity. But that does not mean it is all powerful and will keep going indefinitely. We can undo the links here if they reform with the black magic practitioner making you a target of this dark spirit. So we have you under divine watch, but we are working against the free will of that spirit. Eventually, we will gain the upper hand through a raising of vibration and that spirit will be able to cooperate with light callers and be escorted to the heavenly realm for rehabilitation. That will bring your liberation. So you can know this is in progress. If you stand strong it will help you to not surrender. The level of fear you feel and show this dark being contributes to the problem. It is craving your energy, the emotional suffering in particular, because it is much like you in having had a quite difficult history to end up as a kind of slave of the darkness. Its powers are limited. The problem is what it can do to get your attention and cause sensations within you that are quite unpleasant. So it is a major pest in making you miserable. That does not have to stand and we are working to release you and will keep at it until we succeed.
