The addressees of a preacher invariably exist on the level of materialism. In view of this, if they have the feeling that the preacher of Truth wants to take some material thing from them, they immediately shy away from him. That is why a preacher of Truth never allows any material demand to crop up between his addressees and himself. To the very end, he maintains an atmosphere of selflessness between his addressees and himself. In so doing he may have to bear some material loss. When a preacher proves his seriousness to this extent with regard to his call for Truth, he then becomes entitled to God’s help, so much so that the unbelievers find all their tricks and devices recoiling on them, rendering them unsuccessful in gaining the upper hand.
