Can you tell me about the devotee Amir Shakkar and the unusual treatment Sai Baba prescribed for his illness?

Amir Shakkar was a devotee suffering from severe rheumatism who came to Sai Baba seeking a cure. As detailed in Chapter 22, Baba's remedy was highly unconventional. Instead of a physical medicine, He instructed Amir to stay in the Chavadi. This was a challenging command because the Chavadi was an old, dilapidated, and extremely uncomfortable building. Despite the misery of the place, Amir's complete faith in Baba's word was the true medicine. He accepted the instruction and stayed in the Chavadi for nine months, which ultimately led to his deliverance from the painful ailment.
