Boy do I agree with ^this^ I would never suggest to someone to try and use forceful words or actions. We have no skills as a culture to know what to do with evil..we have so accepted evil intent in our society that it boggles the mind. Trying to give advice to anyone assumes they some how know the basics. This is a wrong assumption on my part. Your understanding is very profound and shows you have the skills needed to address these issues.. My advice is to build energy within oneself. This will over come the negative and by sealing yourself you then can understand that they will avoid you. Positive energy will overflow from time to time and you will learn how to let it out "FOR THE GOOD OF ALL".
But never FEED these evil entities. So many invite them in and then cry foul like if you just asked nice they will leave you alone. That is where the skill comes in. Used to be if someone behaved outside the "norm" in a Religious based culture the first thing they did was take the individual to Church. This acted like meditation in a sacred space. But now even our Churches are taken over and so we have no place to get this connection. I advice study, meditation and care when dealing with issues like this for anyone. I certainly suggest that we come to understand if evil is right there in front of us. Only the very Spiritually grounded individual can help this individual now.
