A man (locked) in the world

What can one do when he/she's locked ?
How does one feel being a prisioner ?

Fortunately, most of us (western civilization persons/peoples) are free, only prisoners inside fortresses imposed by our own mind limitations. You may have heard about the seven sins, this is vaguely the same.

But, how about people in prison ?
How about handicapped people (imprisioned in their own bodies) like tetraplegic or people with sclerosis, hemophilia, diabetes, and so on ?...

Yesterday, I leaned a lot about it.
About physical imprisonment.

And I'm willing to learn more. And more.
But more... I've since learned that someone does not want my presence there. What ?!!! Have we grown yet ?...
