What is the central theme of Chapter 34, and how is it illustrated through the story of the doctor from Malegaon?

The central theme of Chapter 34 of the Shri Sai Satcharitra is the continued glory and miraculous healing power of Sai Baba's Udi. The chapter emphasizes this by narrating a specific, experience-based story to serve as a powerful illustration. It tells of a doctor from Malegaon whose nephew suffered from a terrible bone-cyst that was incurable by any medical means. As detailed in Chapter 34, despite trying all native and foreign treatments, including surgery performed by expert physicians, the ailment persisted. The family, having exhausted all worldly remedies, finally heard of Sai Maharaj. Their journey to Shirdi and their faith in Baba's Udi as a last resort showcases the chapter's message that faith and the grace of a Sadguru can overcome afflictions that are beyond the scope of conventional science.
