Concentration means to fix one's attention on one thing.
It seems to me that if one does that their world becomes smaller, not larger.
Because one is attempting to block out other things in order to concentrate on the one thing.

So I think that your statement is absurd. One can keep the blinders on the eyes just as a man does to the horse that pulls his wagon. It is done so the horse will concentrate on the road and not be disturbed by other things that go on in the road next to him. In this way the horse remains a good servant.

Most people are doing the same thing. They have developed mental blinders so they are not distracted by other stuff that may come to their attention.
Just because other things are going on doesn't necessarily mean that it will cause fear to arise. It only means that awareness of the world has increased.

Hence becoming more aware of other things causes expansion... expanding awareness. And having an expanded awareness is not a negative thing as you are alluding to.

You can deny such things as the NWO and remain shrunken into a small little world of your own choosing. Concentrating on a bright light instead of what the light is illuminating will cause you to become blinded. Beliefs work in the same way. Believing that politicians are not blinded by their own ambitions, that are not deluded by their own visions of grandeur, that they alone will lead you out of darkness, is childish and an immature view. It is a view that does not come from someone who knows what freedom is. It comes from one who enjoys living in a gilded cage. A cage with an open door and the bird doesn't want to leave because it is comfortable with the food, the water that living in a cage offers. Most enjoy being enslaved, preferring not to acknowledge that such a thing as NWO exists.

If you are one of these people, that is fine. But before you point your finger at others, I would make sure that you are standing on your feet, and not on your head, before doing so.

It should be reminded here that one should refrain from attacking the messenger... and concentrate on responding to the message, not the messenger.

The following is from a written article:
"Barack Obama will serve up a New World Order feast like you cannot believe!

That a New World Order is emerging is not in question. The only question is, What will freedom-loving Americans do about it? Of course, the first thing they have to do is admit that an emerging New World Order exists! Until conservatives, Christians, pastors, constitutionalists, and others who care about a sovereign, independent United States acknowledge the reality of an emerging New World Order, they will be incapable of opposing it. And right now, that is exactly what they are not doing."
