How do I take control of unwanted thoughts in my mind?
Mind is a very advanced form of technology which has been master by few. Mind will play all the unwanted things and you can’t do much about that. Our mind will stop when we will be dead. There is no way to stop thoughts moving in our mind.
However, One can consider thoughts as a fragment of imagination which are not true. When you are surrounded my unwanted thoughts. Say loudly in your mind it’s not true and let it pass.
The other way is to hear that thought, consider it as a boring movie which you has to see because you have purchased the ticket. Just listen to thought and make sure that your not going to watch that stupid thought again.
To get rid of the thoughts you have to listen it completely and as the thought is over, just like a boring movie you will never pay attention to that thought again.
