How does Chapter 34 describe the glory and characteristics of Udi?

Chapter 34 continues the narration from the previous chapter, further describing the "glory of Udi." It emphasizes Udi's profound healing qualities through a specific example. The chapter states that a "terrible disease like a bone-cyst (Hadyavran) could not be cured by any remedy," yet "smearing it with the Udi from Sai’s hand completely uprooted the pain." It introduces the story of the doctor's nephew to illustrate this power, noting that word had spread that if Sai Baba, the "great Avaliya," applied Udi with his own hand, "even incurable diseases perish." This chapter portrays Udi not merely as ash, but as a potent, divine remedy capable of succeeding where all other human and medical efforts have failed.
