What is the primary message of Chapter 34 of the Shri Sai Satcharitra, and how is it illustrated?

The central message of Chapter 34 is the immense healing power and glory of Sai Baba's Udi, which is presented as a manifestation of his divine grace. The chapter continues the theme from the previous one, emphasizing that Udi can cure ailments beyond the reach of conventional medicine. This is illustrated through the detailed story of a doctor from Malegaon whose nephew suffered from a terrible bone-cyst, or Hadyavran. As narrated in Chapter 34, despite the efforts of many expert physicians and even surgeons, the boy's condition did not improve. It was only when his parents, in desperation, sought refuge at Sai Baba's feet in Shirdi that a solution was found. Baba gave them Udi to apply to the wound, demonstrating that faith and the Sadguru's grace can conquer even the most incurable diseases.
