Based on the story of the bone-cyst, how does the Satcharitra contrast the power of Udi with conventional medicine?

Chapter 34 uses the story of the doctor's nephew to draw a sharp contrast between the limits of human medicine and the divine power of Udi. The text explicitly states that for the boy's bone-cyst, all native and foreign treatments were tried, expert surgeons were exhausted, and even surgery failed. The disease showed no improvement. In contrast, the remedy offered by Sai Baba was just his Udi. The narrative presents Udi not merely as an alternative treatment but as a definitive cure for a condition deemed incurable by medical science, capable of completely uprooting the pain from a "terrible disease" where all other human efforts were exhausted.
