How does Chapter 34 introduce the healing properties of Udi before telling the story of the doctor's nephew?

Chapter 34 masterfully sets the stage by first proclaiming the glory of Udi. Before delving into the specific narrative, the text makes a powerful statement about Udi's efficacy. It mentions that a "terrible disease like a bone-cyst (Hadyavran) could not be cured by any remedy" but that "smearing it with the Udi from Sai’s hand completely uprooted the pain." By presenting this summary of Udi's power upfront, the chapter frames the subsequent story as an illustrative example of this miraculous quality. The introduction in Chapter 34 serves to build faith and anticipation in the listener, assuring them that the story to follow is a wonderful account based on real experience of Udi's majesty.
