Book as World's Window

People said that book is world's window.
Yes it is.
And it is only a window.
From a book you can see the world, same as you see your garden trough you home window.
Without moving an inch.

But it's not the world.
The real world is out there.
To get there, you have to close your window, and go out.
To get there, you have to close your book, and travel.

You have to experience the real world yourself.
Understand the real world yourself.
And start a journey.
Because book is only a window.
