Once in a very long time you come across a book that is far, far more than the ink, the glue and the paper, a book that seeps into your blood. With such a book the impact isn't necessarily obvious at first...but the more you read it and re-read it, and live with it, and travel with it, the more it speaks to you, and the more you realize that you cannot live without that book. It's then that the wisdom hidden inside, the seed, is passed on.
