A farmer, stricken with a fatal disease, was worried that his sons would be negligent towards the fields, the crops would perish, a his family would be without a cent. So he summoned his sons and told them that there was a great treasure hidden in one of his fields. Accordingly, after their father's death, they searched in all the fields, which, to their frustration, yielded nothing. In response to their wasted digging however, the crops were well plowed and they collected an abundant harvest which sustained the whole family for a very long time. By and by, the sons realized that their well-spent anger was, in truth, the fruit of their own labor.
