Owing to the flood of shallow books which really are exhausted in one reading, the modern mind tends to think every book is the same, finished in one reading. But it is not so. And gradually the modern mind will realize it again. The real joy of a book lies in reading it over and over again, and always finding something different, coming upon another meaning, another level of meaning. It is, as usual, a question of values: we are so overwhelmed with quantities of books, that we hardly realize any more that a book can be valuable, valuable like a jewel, or a lovely picture, into which you can look deeper and deeper and get a more profound experience very time. It is far, far better to read one book six times, at intervals, than to read six several books.
