What was Amir Shakkar's illness, and what unconventional treatment did Sai Baba prescribe for him?

Amir Shakkar was afflicted with severe rheumatism and sought a cure from Sai Baba. Instead of a conventional medicine, Baba prescribed a unique and challenging remedy. As detailed in Chapter 22, he instructed Amir to reside steadily in the Chavadi. This was a difficult order, as the Chavadi was an old, dilapidated, and damp building, home to creatures like scorpions and lizards. Baba's firm words were that Amir should not worry about the poor conditions. Amir's treatment was to accept Baba's word as medicine and remain in that uncomfortable place for nine months, a true test of his faith.
