I think that "Mind is noting but flow of thoughts" Thoughts are coming and going and we also flow with these thoughts thinking that these are our thoughts. In fact these thoughts are not your thoughts therefore "your mind is not your mind" These thoughts are coming from thoughtosphere where lot of thoughts are there and we catch few of them and think that these are my thoughts and I am thinking this, my mind of thinking this and gets distrubed by bad thoughts and then chain starts.
You just have to watch your thoughts, just see it. They would not bother you.
So in conclusion i can say this that "Your mind is not your mind , Your thoughts are not your thoughts"
I hope I am clear enough.
