But it is all in vain that man has reason or learning or imagination if these talents lie sleeping. Not long ago the ruins of an old temple were discovered in Rome. When the spade had turned up the soil, lo, seeds long hidden awakened to cover the soil with rich verdure. For 2,000 years these germs had slept, waiting for the day of warmth and quickening. Thus each faculty of man is latent, until some powerful enthusiasm passes over it. Indeed, mental power is not in the multitude of knowledge acquired, but in the powerful enthusiasms that drive the informed soul along some noble path. Power is not in the engine, but in the steam that pounds the piston; and the soul is a mechanism driven forward by those motives called enthusiasm for learning or influence or wealth. Success might be defined as a full casting of the heart into some worthy cause. It is high time that our young men should recognize that prosperity and wealth are won only when the mind moves enthusiastically along the pathway of industry. Our young men have been deeply injured by the fact that now and then some one stumbles upon sudden wealth, or by accident gains great treasure. But for every one such fortunate person, there are ten thousand who have failed of success for want of a purposeful enthusiasm. The Persians have a strange story of the Golconda diamond mines. Once Ali Hafed sat with his wife looking out upon the river that flowed through their farm. Soon their children came through the trees bringing with them a traveler. In confidence the stranger showed Ali Hafed a diamond that shone like a drop of condensed sunshine. He told his host that one large diamond was worth whole mines of copper and silver; that a handful would make him a prince; that a mine of diamonds would buy a kingdom. That night wealthy Ali Hafed went to bed a poor man, for poverty is discontent. When the morning came he sold his farm for gold, and went forth in search of diamonds. Years passed. Old and gray he returned in rags and poverty. He found his dear ones had all died in penury. He also found that the peasant who bought his farm was now a prince. One day, digging in the white sand in the stream at the foot of the garden, the peasant saw a shining something that sent his heart to his mouth. Running his hands through the sand, he found it sown with gems. Thus were discovered the Golconda mines. Had Ali Hafed dug in his own garden, instead of starvation, poverty and a broken heart, he would have owned gems that made nations rich.
