purgatory is something to fear because, for one, it can be avoided, and also,** it is real pain like we have never felt, and why is that?** well i can’t explain it entirely, because it is a spiritual place and cannot be understood or explained by our physical world, but we know by(as is explained in that book) the visits to the saints from the souls in purgatory, and by what the bible says on it, that it is indeed a place of extreme agony,
we cannot say or believe reasonably that the spirit cannot feel pain like the body can, because we simply have nothing to base that idea off of, but from what the saints have witnessed, we atleast have reason by that to believe it is really and truly pain like we know now, only intensely worse, since they cannot die.
the basic truth of it is, being that it is a spiritual place which we cannot analyze or examine, all we have to go by is what we have been told by either God, those in heaven, or the actual souls in purgatory,
and so what have we been told? here is a book for free online, which you can also buy, called “Read me or rue it”, and it will also explain many things, including what some souls in purgatory have to tell us -

and here are two others by the same author -
2heartsnetwork.org/PURGATORY.doc
2heartsnetwork.org/HowtoAvoidPurgatory.doc
it’s true that the separation from God is much more an immense suffering for the souls in purgatory, but the inflicted pain they go through is still far worse and immense than anything we could ever go through on earth…well, to better understand it just read those books, they are not very long, and they will explain it much better then i can :3
ok hope this helps, take care.
