I read about a man named Amir Shakkar who was sick. What was his illness, and what was Sai Baba's unusual remedy for him?

Amir Shakkar was suffering from a severe case of rheumatism that afflicted his body. As detailed in Chapter 22, he approached Sai Baba and narrated his illness in detail, praying for deliverance from his sorrow. Baba's remedy was not a physical medicine but a simple, firm instruction: he was to stay steadily in the Chavadi. Despite the challenging conditions of the Chavadi, Amir was told to accept Baba's word as the ultimate medicine for his ailment, trusting in the company of Sai over any external comfort or treatment.
