I have a story of my own. Unless I'm dealing with an arcane but respected speciality I'm always suspicious if I can't understand a word of an English text.
I was working with a woman who claimed to channel. She knew I was sceptical so she brought a book which explained it. I couldn't understand a word. She said she would help and asked me to read passages which confused me. Since she wasn't watching closely I just skipped from page to page - a word here, a sentence there. When I'd put together about 6 paragraphs I asked her to explain. She did.
