What is the primary theme or message conveyed in Chapter 34 of the Shri Sai Satcharitra?

Chapter 34 primarily continues the narration from the previous chapter on the glory and majesty of Sai Baba's Udi. It emphasizes that Udi has the power to cure even the most terrible and incurable diseases. As an illustration, the chapter introduces the story of a doctor's nephew from Malegaon who suffered from a bone-cyst (Hadyavran) that could not be healed by any native or foreign medical treatments, including surgery. The central message, as presented in Chapter 34, is that when all other remedies fail, faith in a great saint like Sai Baba and the application of his sacred Udi can provide a solution and alleviate immense suffering.
