How does Chapter 34 contrast the capabilities of conventional medicine with the power of faith in Sai Baba?

Chapter 34 draws a stark contrast between the limits of conventional medicine and the boundless power of faith in Sai Baba. The narrative explicitly states that a degree-holding doctor, his expert physician friends, and intelligent surgeons were all exhausted and helpless in treating the boy's bone-cyst. The text emphasizes that "all native and foreign treatments were tried" and "even surgery was attempted, but nothing succeeded." This failure of medical science sets the stage for the divine intervention of Sai Baba. His simple act of providing Udi, a symbol of his grace, accomplishes what extensive medical efforts could not. This story, as presented in Chapter 34, serves as a powerful testament to the idea that faith and surrender to a Guru can overcome obstacles that are insurmountable by human knowledge and skill.
