How is the healing power of Sai Baba's Udi described in Chapter 34?

Chapter 34 of the Shri Sai Satcharitra describes the glory and majesty of Sai Baba's Udi as a powerful remedy capable of curing even terrible and incurable diseases. It presents the example of a bone-cyst (Hadyavran), stating that smearing the Udi from Sai’s hand completely uprooted the pain from this otherwise incurable malady. The family of the afflicted boy heard that if the great saint Sai Maharaj applied Udi with his own hand, even incurable diseases would perish. This highlights the belief in Udi's divine healing properties, which provide a solution where all other worldly remedies fail.
