Oath,
Not so long ago I found myself being "bothered" by a goetic. In my case it was Andromalius. I had very vivid and bizarre dreams over the course of about a week and a half. One morning I awoke with the name Andromalius in the fore front of my mind. Now, I have never worked with the goetia. I have however read the material. Once I knew the name, I found myself almost obsessed with the entity. I considered evoking the thing to try and figure out what the hell it wanted. After some careful thought I decided that it was probably a bad idea to do so as that may be exactly what it wanted. Instead I immediately started a regimen of banishing until I was certain that I would be bothered no more. It worked. I am still unsure of exactly how I attracted the thing, but at least it is gone.
As far as destroying the entity. Some people consider them parts of the psyche. I would consider it a very drastic and dangerous action to destroy something without fully understanding what you are destroying.
Like I said, I have never worked with the goetic spirits, with the exception of making one leave. Someone more experienced may have a better suggestion. But his is just my two cents.
Good luck! (IMG:
