Can you summarize the events leading up to the family from Malegaon meeting Sai Baba as chronicled in Chapter 34?

Certainly. Chapter 34 chronicles a sequence of desperate events. A young boy, the nephew of a doctor in Malegaon, was suffering from a terrible bone-cyst. His family, which included medical professionals, tried every possible cure. The chapter states that native and foreign treatments, as well as surgery, were attempted by expert and intelligent physicians, but all efforts were exhausted without any improvement. The boy's constant pain and distress left the family worried and helpless. It was only after reaching this limit, where all remedies had failed, that word of a famous saint in Shirdi reached their ears. Believing Sai Baba's Udi could cure incurable diseases, they decided to make the journey as a final hope.
