What does the Sai Satcharitra say about the power of Udi to cure diseases?

According to Chapter 34 of the Shri Sai Satcharitra, the glory of Udi is immense and it possesses incredible healing qualities. The text continues the narration from the previous chapter, stating explicitly that Udi can cure even terrible diseases like a bone-cyst (Hadyavran) when all other remedies have failed. The chapter emphasizes that smearing Udi from Sai Baba's hand can completely uproot pain and suffering. To illustrate this point, the author narrates a story based on a real experience, which demonstrates the profound and miraculous healing power inherent in the sacred ash.
