In an Eastern language there is 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, one asks, "Will anybody convince me, will this thing convince me?" Nothing convinces, 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 the same thing of which faith is the development and conviction the culmination.
