Control of the mind comes with awareness.
Like the old joke about the doctor visit, don't read the news. (the patient said, "Doc, every time I raise my left arm I feel pain." To which the doctor replied, "Then don't raise your left arm.")
Spirit is very powerful and because of it we think the mind has great power. For computation, the mind is great. For more, the mind is as worthless as a rock. Inspiration (in + spirit) comes from spirit -- the true self, the child of God within.
When you read bad news, it stimulates something from your past. If you're aware of this fact, then you can look at "vanish" the effect merely by looking. Most people aren't very skilled at this, so it can be difficult to start to learn. But you have to believe in yourself and in your abilities.
When I had Scientology clearing about 35 years ago, I had a week of perfect quiet in my mind. I'd never felt so much peace. There was no longer any noise -- not a scrap of it. It all came from awareness and practicing the ability of noticing things within the mind.
Like the old saying of Christ, know the truth and the truth will set you free.
If you look at a problem, it will vanish. If you look at it inaccurately, it will persist. So, the next time you think you have a problem and it persists, you haven't looked at it yet. Believe me, it couldn't be any simpler. We humans have a talent for making it too complicated.
And the news? The powerful elite behind the major corporations (including news, military industrial complex and the like) want you to feel disturbed. They're counting on it.
Living 5 years outside of the States has proved to me how vile American news really is. Amazing how distorted it is. I'd heard it before, but had to move here in the Philippines to see for myself.
