What is the primary message conveyed in Chapter 34 of the Shri Sai Satcharitra regarding the power of Udi?

Chapter 34 of the Shri Sai Satcharitra continues to elaborate on the glory and greatness of Sai Baba's Udi. The core message is that Udi possesses immense healing power, capable of curing even the most terrible and incurable diseases where all conventional medical treatments have failed. This is illustrated through the story of a doctor from Malegaon whose nephew suffered from a severe bone-cyst (Hadyavran). As the chapter details, numerous physicians, surgeons, and all available native and foreign treatments could not provide relief. The narrative sets up the central theme that faith in Sai and the application of his Udi can bring about miraculous cures, demonstrating its divine majesty and offering hope to the distressed.
