Bookworm_Girl. Thank you for your comments. I was concerned about the difficulty presented in translation, especially with words that could not be translated and so were left only in phonetic translation. I often wondered whether or not what I was not able to understand was significant or trivial to the story.
My mentioned the issues of Buddhism and the importance of dreams probably goes beyond the discussion of Spring Snow specifically. Having read all four books in the past, and having also recently read Runaway Horses again, I know that these ideas, especially concerning reincarnation, are a continuing thread throughout the tetralogy.
