It is easy for us to say that this is a very hard and fast law. But at the same time it is the most difficult thing to live in this world and to avoid it. One must ask a practical man, a man with common sense, if it is possible to live in this world and not to observe this law of give and take. If the people of the world did no better than keep this law properly there would be much less trouble in this world. It is no use thinking that people will become saints or sages or great beings; if they became just it would already be something.
