This is pretty self-explanatory. Just as a candidate for citizenship in the US has to take classes and pass a test, so too the culture of paradise should be known to all permanent residents. Hence, a paradise prep program administered by anonymous angelic ambassadors, and one which ought not be circumvented by bribery or finagling. Howbeit, if you are Stracci, you might get a pass without doing the classes, for as Jesus said "this very day etc etc". But for those of us who are still alive, this doesn't apply.
Accordingly, anyone who has eavesdropped on engelic embassies enough to be reading this, is invited to ascend the mountain with Vergil as a guide rather than Gollum...in other words, to participate in the "canto a day keeps the confusion away" Dante class this spring as per the Pope's recommendation in Candor Lucis Aeterna. One canto a day every day but Sunday for 16 weeks, and you get 96 cantos, the last three you can do on the spring break if you wish.
