Do we need to close our eyes and go inside to meditate?

You don't HAVE to close your eyes if you can concentrate hard enough to shut out everything around you, but closing your eyes helps.

No, it is easier though to single out a thought when your mind is not being constantly feed information (distractions) from them though. Some focus on an item or light to eliminate such.

Only if you want to temporarily escape reality

It probably couldn't hurt.

no. There are different types of meditation. You can meditate while taking a stroll around the neighborhood. 

If I'm going to meditate I'm going to meditate on the written word of almighty god Jehovah and I can't do that if I can't see the written word of Jehovah.
