How does the narrative in Chapter 34 portray the limits of medical science in the story of the doctor's nephew?

The story in Chapter 34 strongly emphasizes the failure of conventional medicine in treating the nephew's ailment. It pointedly notes that the boy's uncle was a "degree-holding doctor," signifying his professional expertise. Despite this, neither he nor his "physician friends" could find a cure. The text further highlights the limitations of the field by stating that "Expert and intelligent surgeons also became exhausted and felt helpless." By detailing that "all native and foreign treatments were tried" and that even surgery failed, the narrative sets up a stark contrast between the powerlessness of medical science and the spiritual power of Sai Baba and his Udi, which is presented as the only remaining hope.
