Based on Chapter 34, analyze the relationship between conventional medicine and spiritual healing as presented in the story of the doctor's nephew.

Chapter 34 presents a clear hierarchy where spiritual healing, through the grace of a saint, transcends the limitations of conventional medicine. The narrative explicitly states that the boy's uncle was a degree-holding doctor, and he, along with his physician friends and expert surgeons, tried all known 'native and foreign treatments,' including surgery, but were 'exhausted and felt helpless.' This failure of medical science is contrasted with the potential power of Sai Baba. The family's turn to Sai is described as a 'last resort.' The chapter suggests that when human effort and scientific knowledge reach their absolute limit, faith in a higher power, exemplified by Sai's Udi, becomes the only viable path to overcoming seemingly insurmountable calamities.
