Yes the person has to be present and no one else can listen for them
I think the best is to play first the exorcism rite at a low volume for some days then she could get the Plasma Flower and loop it all she can at a low volume too because that cal help calming down, feeling better and more receptive and open to at least listening to advices etc, he would feel loved and in a safe environment and that helps to be open to receive.
She could get the book of cards online version and start working on the cards like to purify the aura, eviction if necessary because more times than not i personally have seen it many times with patients that were trying to overcome addictions that the drugs and alcohol keep them in a very low vibration with weak auras vulnerable to energy vampires, dark entities etc and they try all the can to keep them in that vibration because thats what feeds them.
Then theres one for healing, energy store etc and she can do that for him remotely.
She can also sign up for the energy course that way she can help healing him in the distance, all the while she goes thorough the course or practice using the cards his vibration would be cleaning and raising due to the plasma flower, so when she is ready to start healing he would be receptive.
And she can creates dark and light servitors and train them to keep neutral first his attitude, fears, anxiety and all of those feeling that will surface in the path to clean himself. Basically to assist her with the process.
