Prison

Even prison gives the prisoner space to take two or three steps. The Anchorites that barked themselves up in hollow trees and immured themselves in hollow walls, that perverse man who barrelled himself in a tub, all could stand or sit and enjoy some change of posture. [3]

The worst part of imprisonment is being locked up by yourself. You come face to face with time & there is nothing more terrifying than to be alone with sheer time. Then the ghosts come crowding in. They can be very sinister, very mischievous, raising a thousand doubts in your mind about the people outside, their loyalty. Was your sacrifice worth the trouble? What would your life have been like if you hadnt got involved?
