How does Chapter 34 contrast the efficacy of medical science with the power of Sai's Udi in the story of the boy with the bone-cyst?

Chapter 34 draws a stark contrast between the limits of medical science and the boundless power of Sai Baba's Udi. The chapter explicitly states that the boy's ailment, a bone-cyst, resisted all treatments. His uncle was a doctor, and expert surgeons were consulted, but the text mentions that "All native and foreign treatments were tried; all efforts were exhausted. Even surgery was attempted, but nothing succeeded." This complete failure of established medical practice serves to highlight the extraordinary nature of the Udi. The implication within Chapter 34 is that the Udi operates on a different plane, one of divine grace, succeeding where the most advanced human knowledge and skill had been exhausted and felt helpless.
