Eliminating Negative Thoughts comes first by accepting thoughts as they are, simply thoughts.
How to react in your mind to these thoughts will determine how these thoughts affect you.
With practice you can learn to observe these thoughts and they will gradually pass faster and have a less profound affect, eventually you will laugh when your mind thinks of these thoughts.
Don’t identify any thought as negative because it’s just a thought. Who told you it’s negative? It’s just a thought, you are making it up; maybe you like it.
What’s the problem? f you understand it’s just a thought, it has no power. If you think it’s a reality, then it destroys you. It’s just a thought, isn’t it?https://www.youtube.com/watch?v=dDhyUu-3CDY
