A book is not only a friend, it makes friends for you. When you have possessed a book with mind and spirit, you are enriched. But when you pass it on you are enriched threefold.
My understanding of the meaning of a book is that the book itself disappears from sight, that it is chewed alive, digested and incorporated into the system as flesh and blood which in turn creates new spirit and reshapes the world.
On Destiny: "Our destiny exercises its influence over us even when, as yet, we have not learned its nature: it is our future that lays down the law of our today."
