Based on the story of the doctor's nephew, what does Chapter 34 suggest about the limits of medicine and the power of faith?

Chapter 34 presents a clear narrative where medical science reaches its absolute limit. A degree-holding doctor, along with other physicians and surgeons, used all their 'native and foreign treatments' and even surgery, but were ultimately helpless against the boy's severe bone-cyst. It was only after all these efforts were exhausted that the family turned to a spiritual solution. They heard of Sai Baba, a great Avaliya whose Udi could 'perish' incurable diseases, and went to him as a 'last resort.' By having Sai Baba successfully intervene with just Udi after medicine failed, the chapter suggests that faith and the grace of a Sadguru possess a power that transcends the limitations of conventional science, offering a solution where all other remedies have proven ineffective.
