You have probably seen manufacturers of glass frames scoring the surfaces of sheets of glass with a pen-like instrument, then neatly snapping them into two. The cutting edge of this tool is made up of small razor-edged diamonds. Even the huge drills used for boring through hundreds of feet of rock strata in the search for oil are fitted with diamond cutting edges. It is the extreme hardness of the diamond which makes these tools so effective. The diamond is, in fact, the hardest known naturally-occurring substance. It cannot even be scratched. Put it in acid, and there will be no effect. But there is another aspect to this wonderful stone. If it is heated to a very high temperature it will disappear-it will simply sublimate into carbon dioxide, and if struck a sharp blow at exactly the right point, it will break asunder. You have only to look at diamond gemstones to see what exquisite, multi-faceted forms they can be given by jewellers, because, by studying the inner structure of the diamond, they know exactly where and how to break them.

Similarly, when we find ourselves in difficult situations, we should study them carefully, in the way that the jeweller studies his diamond. We should not approach them, carelessly, from the strongest point, but with circumspection, from the weakest. We should not adopt methods which are likely to gain poor results like aggressiveness or violence, for these only engender bitterness and obstinacy in others. We should resort to politeness and diplomacy-eschew harsh language in favour of gentleness and tact.

We should consider also that there are certain human beings who are known as "rough diamonds." That is, on the outside they appear to be unattractive and without merit, whereas on the inside they are of great worth. To bring out their worth, so that their true value is apparent to society, it is pointless scratching at the surface or using acid. If the upright human soul is to be revealed in all its beauty it must be given the same delicate handling and treated with the same expertise as the master craftsman lavishes on a superb but fragile piece of jewelry.
