Harmful effects of Distrust

One may recall a fairy tale—A thinker brought some people a wonderful curative remedy, but it was necessary to carry it in a closed casket. None of the people would consent to open this casket, because, judging by their own natures, they assumed that it was a viper or some kind of poison. Thus one may offer a most beautiful treasure, but people will take it to be poison. This is how people impelled by fears of misfortune accept a treasure. What, then, is to be done if Satan has so firmly implanted distrust.
