People always ask what benefit they will get; and they are more concerned with benefit today than ever before. In no age have people been so anxious to make profits as today, and they will give their life for it. It does not mean that a man today is less inclined to make a sacrifice; he is as ready to make sacrifices as a thousand years ago or even more so; only, he must be sure of what he can get by it. He is so concerned with gain that he always has gain in his view. Even when there is something that does not show immediate profit, and when he does not quite know what or how much profit there might be, he thinks, "Well, perhaps this is something I can get without sacrifice." It is strange.
