What is the primary message conveyed in Chapter 34 regarding the power of faith versus medicine?

Chapter 34 powerfully illustrates the theme that faith and divine grace can triumph where conventional medicine fails. The narrative centers on a doctor's nephew suffering from a bone-cyst, an ailment that stumped the boy's own physician uncle and other expert surgeons. After all native and foreign treatments were exhausted, the family turned to Sai Baba as a last resort. As detailed in this chapter, Sai Baba's simple remedy of Udi, coupled with his divine assurance, is presented as the ultimate solution. The story thus guides the reader to conclude that surrendering to a Sadguru with faith holds a power far greater than human medical expertise.
