Based on the story of the doctor's nephew, how does the Sai Satcharitra portray the power of Udi in comparison to conventional medicine?

Chapter 34 of the Sai Satcharitra portrays Udi as a divine remedy that succeeds where all conventional medicine fails. The narrative systematically establishes the limits of human expertise by noting that a degree-holding doctor, his physician friends, and even expert surgeons were helpless against the boy's bone-cyst. All native, foreign, and surgical treatments were exhausted without success. In stark contrast, Udi, given by Sai Baba, is presented as the ultimate solution capable of uprooting the pain from a "terrible disease" that was otherwise incurable. This illustrates a central theme: the supremacy of spiritual grace and its physical manifestation in Udi over worldly remedies.
