Describe how the introduction of Chapter 34 frames the story of the doctor's nephew to emphasize the glory of Udi.

Chapter 34 of the Shri Sai Satcharitra skillfully sets the stage to highlight the power of Udi. The introduction explicitly states that it continues the narration on the 'greatness of Udi' from the previous chapter. It immediately makes a powerful claim, stating that a terrible disease like a bone-cyst ('Hadyavran') that could not be cured by any remedy was completely healed by smearing it with Udi from Sai's hand. The text then promises to narrate a story as an illustration. This is followed directly by the account of the doctor from Malegaon, whose nephew suffered from this exact type of ailment, a bone-cyst ('Hadyavarn'), that had resisted all medical treatments. This framing presents the nephew's case not just as a story, but as direct, experienced-based proof of the Udi's miraculous healing properties mentioned in the chapter's opening lines.
