There lived an old farmer . He had four sons . They were very lazy .
He wanted to teach them the value of hard work . But the lazy sons did not care for his advice .
One day , the farmer fell ill . He was on death bed .
He called his sons and said , ” I have buried a treasure in my field .
But I do not remember the exact place . Dig it out after my death . ” After the death of their father , they went to the field .
They dug it from end – to end . But they found no treasure .
They became sad . In the mean time , an old man passed that way .
He knew what their father meant . He advised them to sow seeds .
They acted upon his advice . They reaped a rich harvest .
They became rich . Thus they learnt the value of hard work .
Moral : No pain , no gain .
