What kind of 'medicine' did Sai Baba prescribe for Amir Shakkar's rheumatism, and what were the conditions of his treatment?

For Amir Shakkar's severe rheumatism, Sai Baba prescribed a unique and challenging treatment. Instead of a physical remedy, Baba's medicine was His word and command. As detailed in Chapter 22, he instructed Amir to stay steadily in the Chavadi for nine months. This was an arduous test of faith, as the Chavadi was a dilapidated, damp, and filthy place, seemingly counterintuitive for healing rheumatism. The text explicitly states that Baba's medicine was only His word, and Amir, accepting this, had to endure terrible living conditions with internal faith that this was his path to recovery. He was even forbidden from going to the Masjid for Baba's darshan during this period.
