There are others who learn from books. I have known some people who had written perhaps fifty or a hundred books themselves, and had read may be a whole library, yet they still remained standing in the same place where they were. As long as one's face is not turned away from that end which is the end of limitation, and as long as one does not look towards that ideal of perfection which is the real Ka'ba or place of pilgrimage, one will not arrive at that perfection.
