Describe the power and glory of Sai Baba's Udi as illustrated in the story from Chapter 34.

Chapter 34 continues the narration on the greatness of Udi, presenting it as a substance with divine healing properties. The chapter emphasizes that Udi from Sai's hand could completely uproot the pain of even a terrible disease like a bone-cyst (Hadyavran), which other remedies could not cure. The story of the doctor's nephew serves as a prime illustration of this power. His family, having exhausted all medical options and finding no help from other deities, placed their final hope in Sai's Udi. They had heard that if the great Avaliya applied Udi with his own hand, even incurable diseases would perish. This belief drove them to Shirdi, and Sai Baba Himself instructed them to take the Udi and smear it on the wound, reinforcing its role as a divine remedy.
