I agree with your blog - Don't Do It!
Just do what you can to get rid of it. I may have become a bit more callous when dealing with negative entities than many people but, I have run across so many in the past, I have felt their impact upon myself, I have heard from others how they are impacted or have witnessed the change in others first hand. I have come to the point where if they are negative they have got to go!
I used to do it myself. Unfortunately in the past several years I have run into an increasing number of negative entities that refuse to go or they go for a few days or few weeks and come right back.
A few months ago I was going through some old audio files, talk show interviews, and ran across one with Doreen Virtue. Now I just ask Archangel Michael and all other Angels present to get rid of it or do something about it.
It has been remarkably successful.
Oh well, just my personal opinion.
