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

Amir Shakkar was afflicted by severe rheumatism and sought a remedy from Sai Baba. As detailed in Chapter 22, instead of a conventional medicine, Baba instructed him to stay steadily in the Chavadi. This was a challenging instruction because the Chavadi was an old, dilapidated building with terrible living conditions, including dampness, cold, and the presence of scorpions. Despite his misery, Amir had to follow Baba's firm words, which were considered the true medicine. He was told not to worry about whether the place was high, low, windy, or damp, and to accept the company of Sai as the ultimate blessing.
