Who was Amir Shakkar and what did Sai Baba instruct him to do for his illness?

Amir Shakkar was a man suffering from a severe case of rheumatism who came to Sai Baba seeking a remedy and deliverance from his sorrow. As detailed in Chapter 22, after Amir explained his ailment, Baba's prescribed cure was for him to stay steadily in the Chavadi. Despite the Chavadi being a dilapidated and uncomfortable place, Amir accepted Baba's word as his medicine. This instruction led to a nine-month stay in that location, which was a test of his faith and obedience.
