How does the story of the Malegaon doctor's nephew contrast the limits of medical science with the power of Udi?

The story in Chapter 34 serves as a powerful illustration of the theme of spiritual power transcending the limits of medical science. The narrative carefully establishes that the highest levels of medical expertise were applied to the boy's bone-cyst. His uncle was a doctor, and 'expert and intelligent surgeons' were involved, yet they all 'became exhausted and felt helpless.' This highlights the boundary of conventional treatment. In stark contrast, Sai Baba's intervention was simple and spiritual: the application of Udi. The text presents Udi as the remedy for what was otherwise an 'incurable' disease, demonstrating its glory and majesty. The story positions faith and Sai's grace, embodied by the Udi, as the ultimate solution when all other human efforts have failed.
