I've heard that she believes there's more evil than good in the world - that makes me so sad, I'd hate to believe it. It's much nicer to believe that everyone is good and wonderful, at least in some way :) But then again, I'm an optimist and stubbornly naive idealist.
I'm curious though, does anyone have any more info on this? What are grey/black/white souls? I read one of her books, and she said truly evil people (ie. Hitler) are just reincarnated again and again in an endless cycle? I understand that they wouldn't go to Heaven, but why Earth? But then again SB is also quoted as saying Earth is hell..
