What is Chapter 34 of the Shri Sai Satcharitra primarily about?

Chapter 34 of the Shri Sai Satcharitra continues the discussion from the previous chapter on the glory and miraculous power of Udi. The chapter's introduction explicitly states it will further narrate the qualities of Udi. To illustrate its power, the chapter presents the story of a doctor from Malegaon whose nephew suffered from a painful and incurable bone-cyst, also known as Hadyavran. As detailed in Chapter 34, after all medical remedies failed, the family sought Sai Baba's help in Shirdi, demonstrating the profound faith people placed in his divine healing abilities and the sacred ash from his fire.
