What was the nature of Sai Baba's 'medicine' for Amir Shakkar's rheumatism?

Sai Baba's treatment for Amir Shakkar's rheumatism was not a physical substance but a profound test of faith and endurance. Chapter 22 reveals that Baba's medicine was simply His word. He commanded Amir to stay in the dilapidated and uncomfortable Chavadi for nine months, despite conditions that were externally contrary to healing—dampness, cold, and filth. Baba's firm instruction was to ignore the wind, rain, or lowliness of the place. The cure was predicated on Amir's internal faith and his acceptance of Baba's word as the ultimate remedy, proving that steadfast belief was more powerful than the adverse physical environment.
