1.  It's a                 book.
2. It was first published in the year  1871.
3. It contains the writer's opinions and speculations about the possibilities of what the glories of  Heaven may be like. Certainly there is no guarantee or expectation that every sentence in it should be relied on as being Infallible or absolute truth. Basically that means that when reading it you can feel free to "hear what you want to hear and disregard the rest."  --As a once popular song has told us to do.
  A radio talk show host once said "I don't read the way that other people do, I scan for nuggets." THERE ARE
nuggets  in this book so therefore that's a suggested way of READING IT.
4. The book was written by a Catholic person. A deeply Christian Catholic person.
Does the fact that he had traditional Catholic views mean that Jesus did not welcome him {with Love} into His Eternal and Heavenly Kingdom?
Well... Feel free to  READ THE BOOK!!!!!!  See what conclusions you come up with about that question! 
If you are not a Catholic why not just skim over any Catholic references in the book and just not be bothered by them?
It's a choice. You can open the book with the intent to look for faults or you can look for charm and glory.

5. The {messy} underlining in the book was done for the person who  underlined it.  It was not underlined (for others) with the intention of scanning it into a computer and putting it on the internet.  One day it just kind of  popped into existence as a PDF book.    IF the underlining seems a little wacky just consider it as residual effects from the underliner eating too many mushrooms as a kid. "Can anyone tell me when the furniture is going to stop melting?" --It is recommended to not do activities that lead to having questions such as that.
