The villain Bane, put him there after he kicked Bruce Waynes butt in a fight. This is a prison that Bane had allegedly been in.
Bruce works on trying to escape.
First by working out and building his body back up after having his back broke in the fight with Bane.
This confuses a couple of prisionsers. They ask, "Why do you build your body back up?"
Bruce says, "to make the jump."
One prisioner responds, "Survival is the spirit. The soul."
Bruce ignores them and keeps working out and attempting to escape.
The only way to escape the prison is to climb the wall. Then at a certain point, you must make a long leap to grasp a piece of the wall. If you don't make this jump, you would surely fall to your death.
So, to make sure he doesn't fall, in case he can't make the jump, Bruce ties a rope around his waste, to catch him.
This happens over and over again. Bruce coming up short on the jump, the rope he is tied to, saving his life.
Finally one night the prisoner says to Bruce...
Prisoner: You do not fear death. You think this makes you strong. It makes you weak.
Prisoner: How can you move faster than possible, fight longer than possible without the most powerful impulses of the spirit: the fear of death.
Bruce: I do fear death. I fear dying here, while my city burns, and there's no one there to save it.
Prisoner: Then make the climb.
Prisoner: As the child did. Without the rope. Then fear will find you again.
My favorite part, the next morning Bruce is packing supplies, water, food into a blanket. He climbs the wall, but this time... No rope to save him.
Fear does not need to be absent of confidence.
