How does Chapter 34 emphasize the failure of medical science before introducing Sai Baba's Udi as a cure?

Chapter 34 strongly highlights the limits of conventional medicine through the story of the doctor's nephew. The text explicitly mentions that the boy's uncle was a "degree-holding doctor," yet his own expertise was insufficient. Furthermore, it details how his physician friends, "expert and intelligent surgeons," and both "native and foreign treatments" were all tried without success. Even surgery was attempted, but "nothing succeeded." This comprehensive failure of all known medical remedies, as described in this chapter, serves to underscore the miraculous nature of the cure that was to be provided by Sai Baba's Udi.
