What is the punishment of purgatory?

The Catholic Answers

When the soul leaves the body, that which can think, remember, love, hate, be happy or miserable, has gone from that body. A corpse cannot do these things. And the soul, with these capabilities, goes into a new state of being as a separated spirit. And my true self, separated from the distractions of this world, will perceive clearly and fully its own unfitness for God’s presence, a perception which will mean unspeakable suffering. The exact nature of this suffering we do not know, but it is compared in Scripture to the action of fire afflicting a sensitive body. Although it is not defined as a dogma that there is a real fire of purgatory, it is the general opinion of theologians that there is a real fire somewhat analogous to the fire of hell. However it be explained, the fact that purgatorial suffering awaits the imperfect has been revealed by God.
