What are these great mountains of misery?

Many are imprisoned in these mountains who may not yet be helped out by any, for they would only be a danger to others were they free. The ruin and evil they would shed around them make their longer imprisonment a necessity. Yet their prisons are of their own creating, for these great mountains of misery are the outcome and product of their earthly lives and these precipices are the spiritual counterparts of those precipices of despair over which they have driven their unhappy victims. It is not until their hearts soften and they learn to long for liberty that they may do good instead of evil―only then will their prisons be opened and they will be drawn forth from the living death in which their own frightful cruelties to others have entombed them.
