The main theme could be about family and inheritance. Since a son is born to a rajah, there might be elements related to the passing on of power, status, and family legacy within the context of a rajah's family.
In this short story, we would surely find the rajah as a central character. His personality and decisions would shape the story. The new - born son is another key character, his very existence being the catalyst for the events in the story. The mother of the son is important too, her relationship with the rajah and her role in the upbringing of the son would be part of the narrative. Additionally, there could be priests or holy men in the story, as in many royal families, religious figures play an important role. They might be involved in rituals related to the birth, or offer prophecies about the son's future.
One possible plot could be that the son's birth is seen as a sign of good fortune for the rajah's kingdom. Another might be that there are rivalries within the court regarding the new - born son, as some may see him as a threat to their own power.
It could be a tale of great expectations and responsibilities, as the son might be destined for a significant role in the future of the rajah's domain.
Since I'm not familiar with the exact 'a son is born to a rajah' story, I can only speculate. In a typical scenario, the birth of a son to a rajah would be a cause for celebration. The queen who gives birth might be highly honored. The newborn son would be the center of attention. Courtiers would start planning for his education and training in the ways of leadership. The common people might also look forward to the new prince, hoping he would be a just and benevolent future ruler.
One possible main theme could be the burden of expectations. Since he is the first born son, there are likely a lot of hopes pinned on him, which can be a heavy load to carry.
The main theme might be family bonds and the cycle of life. It could focus on the hopes and dreams parents have for their new-born son.
Since I don't know the 'A Son is Born' short story precisely, I can only guess. It might be about the challenges and joys that come with the birth of a son. It could tell a story of the mother's experience during pregnancy and childbirth, and then how the family adapts to having a new member. It might also touch on cultural or social aspects related to the birth of a male child in the context of the story, such as inheritance, family name continuation, or gender - specific expectations in that particular society.
I haven't read the 'A Son is Born' short story, so I can't say for sure who the main characters are. But I would assume the son himself would be a main character, and probably his parents too.
It could be about the passing on of wisdom from one generation to the next. The mother uses her own life journey, which is filled with hardships, to teach her son valuable lessons. By comparing her life to a rough staircase, she implies that he should also be strong in the face of difficulties in his own life.
The main theme is the complex relationship between a son and his parents, especially the challenges and changes as the son tries to care for his aging parents.
