According to Chapter 34, what was the nature of the disease that afflicted the boy from Malegaon, and why did all medical treatments fail?

Chapter 34 describes the boy's ailment as a 'bone-cyst' (Hadyavran), calling it a 'most difficult and extraordinary malady.' The reason for the failure of medical treatments was the severity and unusual nature of the disease, which seemed to be beyond the scope of conventional science at the time. The text explicitly states that the boy's uncle was a doctor himself, and he, along with 'expert and intelligent surgeons,' felt 'exhausted and helpless.' All efforts, including 'native and foreign treatments' and even surgery, were attempted but proved entirely unsuccessful. The narrative in Chapter 34 uses this failure to highlight a key point: there are limits to human remedies and intellect, setting the stage for the miraculous spiritual healing provided by Sai Baba's Udi.
