What was the true 'medicine' for Amir Shakkar's rheumatism, and how long did his treatment last?

The true remedy for Amir Shakkar's rheumatism was not a physical substance but his unwavering faith in Sai Baba's command. As stated in Chapter 22, Baba's medicine was simply His word. Despite the externally contrary conditions of the damp, cold, and dilapidated Chavadi, which would seem to worsen rheumatism, Amir had certain internal faith. He accepted Baba's firm words as the ultimate medicine and stayed happily. This unique 'treatment' was ordained for a period of nine months, during which he was to remain in the Chavadi, demonstrating that the healing process was rooted in obedience and internal conviction rather than external comfort.
