There is in Arabic a word which is very difficult to translate: Iman. It is not exactly faith or belief; the nearest word one can find for it is 'conviction', a conviction that cannot be changed by anything, a conviction that does not come from outside. One always seeks for conviction, but nothing convinces and nobody convinces; conviction is something that comes from one's own heart, and it stands above faith and belief; for belief is the beginning of that same thing of which faith is the development and conviction the culmination.
