He said-
I can tell about a person or an animal by looking at his face.
The king made him his special "incharge of the horse stable".
After a few days, the king asked him his opinion about his most expensive and favourite horse, he said..
The horse is not purebred.
The king was surprised,
He called the horseman from the forest and asked him. The horseman told the king that the horse is purebred, but its mother died as soon as it was born. So it drank the milk of a cow and grew up with it.
The king called his servant and asked him how he came to know that the horse was not purebred??
"He said- "When it eats grass, it eats with its head down like cows, whereas a purebred horse takes the grass in its mouth and raises its head."
The king was very happy with his ability. He sent food grains, ghee, chickens and many goats to the servant's house as a reward.
And now the servant was posted in the queen's palace.
After a few days, the king asked him his opinion about the queen.
He said, "Her manners are like a queen, but not a born queen."
The king was shocked. He called his mother-in-law.
The mother-in-law said...
"It is true that your father had asked for a marriage proposal from my husband when our daughter was born but our daughter died in 6 months. So, to stay close to your royal family, we made someone else's daughter our daughter."
The king again asked his servant, "How did you know?"
He said, "The queen's behaviour with servants is worse than that of uneducated people.
A noble person has a way of behaving with others, which the queen does not have.
The king was again pleased with his discerning eyes,
and again gave him a lot of grain and sheep as a reward.
The servant was posted in his court now!
Some time passed,
The king again called the servant, and asked about himself,
The servant said,
"If my life is safe, I will tell you."
The king promised, then the servant said, " You are not the son of the king"
The king got very angry but he had promised to spare his life. The king went straight to his mother's palace.
The mother said, "This is true.You are the son of a shepherd, we did not have children, so we adopted you and raised you."
The king called the servant and asked, "Tell me how did you find out about this?"
He said, "When kings reward someone, they reward them in the form of diamonds, pearls and jewels but you give sheep, goats, milk and ghee. This attitude cannot be of a king, but can only be of a shepherd's son."
The reality of a person is identified by his behaviour.
