When wheat is harvested, most of it is taken by truck to a grain storage facility—called an elevator—from which it is carried away as needed by trucks, railroad cars, or barges to grain wholesalers, exporters, and local end-users, such as flour mills, breweries, and alcohol distilleries.
The movement of tons of wheat generates a cloud of dust within the elevator, and if the operators are careless, this dust can become the fuel for a massive explosion. In short, wheat can give life, or—if improperly handled—it can kill.
It is similar with human beings. Our association with them—if guided by Real Love—can give emotional, psychological, and spiritual life. If not, the effect on us by others can become deadly. We are wise to choose well our associates.
