How does Chapter 34 use the story of the Malegaon doctor to contrast the limitations of medical science with the power of a Sadguru's grace?

Chapter 34 masterfully illustrates the theme of faith transcending the limits of science. The narrative emphasizes that the afflicted boy's uncle was a "degree-holding doctor" and that "expert and intelligent surgeons" were involved. They applied "all native and foreign treatments" and even performed surgery, representing the pinnacle of medical effort, yet they "became exhausted and felt helpless." It is precisely at this point of complete failure of human expertise that the family turns to Sai Baba. His simple remedy of Udi, a symbol of divine grace, is positioned as the solution where science failed. This stark contrast serves to reinforce the chapter's core message that a Sadguru's power operates beyond the boundaries of conventional knowledge and remedies.
