What does Chapter 34 reveal about the reputation of Sai Baba and the power of his Udi, particularly concerning the story of the doctor's nephew?

Chapter 34 underscores the immense reputation of Sai Baba as a great saint, or Avaliya, and the miraculous power of his Udi. The story of the doctor's nephew serves as a powerful illustration. The family only heard of Sai Baba after all expert physicians, surgeons, and various treatments had failed to cure the boy's severe bone-cyst (Hadyavarn). Word had reached them that Sai Maharaj, the King of Yogis, could heal diseases just by his sight and that if he applied Udi with his own hand, even incurable diseases would perish. This chapter presents this belief not as mere hearsay but as an experiential truth, culminating in Sai Baba providing the Udi as the ultimate remedy.
