I don't think I have any kind of specific ritual for reading books but what I do have is an extreme sensitivity to anything that can disturb my reading. For instance I can't read in a room where others are chatting or worse, when others are watching television. It slows down my comprehension of the book I'm reading to the point I end up taking half an hour to read just a page. So I'm always trying to find places where there is quiet to enjoy my readings. But this is no simple task as there is always someone around to break the quiet. I guess that looking for a quiet place to read could be considered like my reading ritual
