What was Amir Shakkar's ailment, and what was Sai Baba's prescribed treatment for him?

Amir Shakkar was afflicted by rheumatism and sought a remedy from Sai Baba. Instead of a conventional medicine, Baba's treatment was a test of faith and endurance. As detailed in Chapter 22, Baba instructed Amir to stay steadily in the Chavadi for nine months. This was his sole medicine. Amir was even forbidden from visiting the Masjid. The cure was to accept Baba's word and endure the difficult conditions of the Chavadi, trusting in the presence of Sai, who stayed there on alternate nights.
