You gotta read the Purgatorio (largely because it's the work that made me fall in love with Dante.)
I'm wanting to pray for the speedy and as easy as possible accomplishment of purgation, how's that?
Anyway I still stand by my distinction between useful and useless or less useful suffering. In any event I'm trying to get away from the notion of quanta of pain as recompense for quanta of sin.
I wish you were MY doctor. I didn't get no pain killers, unless you count ibuprofen.
It is actually a prayer that God in His mercy foreshorten the need for the suffering. At this hour, language fails me, so I will badly oversimplify it as a request that a judge reduce sentencing, or that the teacher let the student out of detention early.
