Radha was a milkmaid. She was carrying a pot of milk.
She had to deliver milk to her customers in a nearby village. As she was walking she kept on dreaming.
She said to herself, “With the money I get from selling this milk, I will buy some eggs. The eggs will hatch into fine chicken. The chicken will grow into hens. I will sell the hens and get lot of money. With that money I will buy nice silk saree. I will look beautiful. When people ask for the secret of my wealth, I will toss my head and say, “No.”
When she dreams of saying ‘No’ She actually tossed her head and down fell the pot of milk and all the milk ran out on the ground.
MORAL : Building castles in air will not stand.
