Hi,I'm not near the adept person that others are that I read,and I would consider their advice first,its just that I was remembering something that I figured out when I read your request.I used to have a problem with what I was thinking to the point where it really was a crummy way to suffer.My mind kept racing around from one problem to anouther problem to where I felt like I was out of control against my own will.So I decided to track my brain.I figured that the brain is a mostly logical organ and therefore should be more predictable,and my idea was to track my thoughts,and see where they where going,to,(like in patterns).So what I figured was I would get a piece of paper,and when one subject came up,I would write it down in a box on the piece of paper,and when each new subject came up,I would draw anouther box for it and put it in there (like tic,tac,toe,only bigger).Then when the same subject came up again I would give it a mark (like when you count four marks and the fith one is a forward slash through the others).Ifigured that way I could track my brain's thinking,(or lack thereof) and watch where it was going.When it hit the same subject,I would be able to point it out to myself,(to my brain or mind),and say "nope,that one's already been done",and see where my thoughts would go from there.I figured that if I pointed it out to myself that I couldn't get away with thinking diumb or useless thoughts right in front of myself anymore.The brain is logical,and when you can look right down and see the subject as its hitting on it,it will take anouther course and free itself from repetitous thinking.That might get you off of the suject of blasphemy,poor thinking,depressing thoughts,its not natural for you to have cruel thoughts that you don't like.The other thing is you might consider praying to the Lord that you want any trespassers kicked out,telling Him that you want any of them around to suffer the same harassment on a lower plane then you,besides anything else they deserve to get.Make it personal.Good luck.
