How does the story in Chapter 34 serve as a continuation of the theme of Udi's greatness from the previous chapter?

Chapter 34 explicitly states in its introduction that it is a continuation of the previous chapter's theme: the greatness of Udi. The story of the doctor's nephew with the incurable bone-cyst is presented as a specific, experience-based illustration of this glory. The chapter meticulously details the failure of all conventional medical knowledge, including expert surgeons and both native and foreign treatments. This deliberate emphasis on the hopelessness of the situation serves to magnify the power of Sai's simple remedy. By having Sai give Udi as the solution to an 'incurable' disease, Chapter 34 powerfully demonstrates that the sacred ash's healing properties transcend the limits of human science and effort.
