Why people get entities, attachments and possessions
People often think that spiritual entities, attachments and possessions are the work of the devil or some evil force that is working against them. In certain scenarios - such as psychic attack from a third party - this can be true. But from a human - indirectly.
However - the reality to this situation is a very different one, from what you might expect. All such situations are actually governed by the individual's higher-self - nearly always as some kind of wake up call.
The divine know how humans are - unless we are really bothered by something, we are unlikely to change course, or even our ways regarding something we may be doing wrong or should not be experiencing.
So entities and attachments are actually given by the divine in an effort to wake us up and to seek help at some level.
Normally when the individual in question takes the right action or seeks guidance and is told by a suitable intuitive what is going on and why - the persons higher-self will make arrangements for removal and energetic repair.
