What is the main story used to illustrate the power of Udi in Chapter 34 of the Shri Sai Satcharitra?

Chapter 34 of the Shri Sai Satcharitra continues its praise of Udi's glory by narrating a specific, experience-based story. It details the case of a doctor from Malegaon whose young nephew suffered from a severe and painful bone-cyst, referred to as Hadyavran. As this chapter explains, the doctor, along with other expert physicians and surgeons, tried every available native and foreign treatment, including surgery, but all efforts failed to provide any relief. When all medical remedies were exhausted, the family heard about Sai Baba of Shirdi and decided to seek his divine help as their last resort, showcasing a situation where faith was the only remaining option.
