I find the topic one of diverse and often strong opinions. In my own experience, most of the entities we find are either from other dimensions or are forms of energy, not trapped souls. I also find that the vast majority of the time, people and paranormal entities can co-exist peacefully and well. There are exceptions of course.
Then comes the question of do the clearings/blessings work? I have experienced a small number. One was done by well intentioned people from a non-denominational Christian background. Though the people involved with the clearing were saying it worked, I saw the entities laughing and mocking them. And the activity continued, and got worse.
I also know of cases where the entities were sent away, briefly, but came back with friends. If the site isn’t also sealed against return, a cleansing can do far more harm than good. The vacuum left is filled, often by entities that are nastier than the ones originally there, or else the old ones return with friends!
I’ve been to one cleansing that I could feel and see worked. It was last weekend. Native American traditions were at least part of the process, and the right plants were burned and ceremonies used to seal the property. That doesn’t mean the residents can’t open the door again. That’s always possible.
To me, cleansings are something that should only be done by expert with strong experience and knowledge in both removing what’s there, and keeping anything from returning! What are your thoughts?
