I've known several people who think this is the most wonderful book they've ever read. I must say, I just don't get it. New Age drivel! If you must read this sort of thing, try The Prophet by Kahil Gibran (a tad insipid, but fairly well written).

Of course, if you just want to read something by a Brazilian or Portuguese author, I enthusiastically recommend the works of Antonio Machado de Asis or Jose Saramago. I guarantee that you will find very little pre-digested chicken soup for the soul in their books.
