Explanation:

The story:
The story is about a courtier who challenged the emperor that he could achieve the impossible. The emperor was curious and asked him to do so. The courtier then went on to ask Gopal, a wise man, to help him achieve the impossible.

Gopal’s wisdom:
Gopal, in turn, asked the courtier to bring him a pot full of mustard seeds from a house where no one had ever lost a child, husband, or wife. The courtier thought it was an easy task and went from house to house in search of such a house. However, he could not find a single house where no one had ever lost a loved one.

Gopal’s lesson:
The courtier realized that it was impossible to find such a house. He returned to Gopal and told him so. Gopal then taught him an important lesson that death and loss are a part of life and no one can escape it. He also advised him to never make false promises or claims.

Gopal’s achievement:
Gopal’s wisdom had helped the courtier realize the futility of his challenge to the emperor. However, Gopal’s own achievement was that he had imparted a valuable lesson to the courtier and helped him become a better person.

Gopal’s wife:
Gopal’s wife also played a significant role in the story. She had advised Gopal to give the courtier a task that would teach him a lesson. Thus, she was indirectly responsible for the courtier’s transformation.

The impossible:
In the end, it was Gopal who had achieved the impossible – he had helped the courtier become a better person and learn an important lesson.
