What is the central message regarding Udi conveyed in Chapter 34 of the Shri Sai Satcharitra?

The central message of Chapter 34 is the immense and divine power of Sai Baba's Udi to heal ailments that are beyond the scope of conventional medicine. The chapter continues the theme from the previous one, aiming to describe the 'majesty of Udi' further. It uses the story of the doctor's nephew and his incurable bone-cyst as a prime example. The narrative explicitly states that a 'terrible disease like a bone-cyst (Hadyavran) could not be cured by any remedy,' but smearing it with Udi from Sai’s hand 'completely uprooted the pain.' Thus, Chapter 34 reinforces the belief that Udi is not a mere ash but a potent symbol of Baba's grace and protection, capable of performing miracles.
