How does Chapter 34 illustrate the immense power of Sai Baba's Udi?

Chapter 34 continues the theme from the previous chapter by further describing the glory and characteristics of Sai Baba's Udi. It provides a powerful illustration through the story of a doctor's nephew from Malegaon. The boy suffered from a terrible bone-cyst that was deemed incurable by any medical remedy, including surgery. As detailed in this chapter, after all efforts failed, the family sought Sai Baba's help. Baba, the embodiment of compassion, reassured them and gave them Udi to smear on the wound, demonstrating that his Udi could uproot even the most difficult and extraordinary maladies.
