What cure did Sai Baba prescribe for Amir Shakkar's rheumatism, and what were the conditions he had to endure?

When Amir Shakkar, who was afflicted by rheumatism, prayed to Sai Baba for deliverance from his sorrow, Baba gave him a unique remedy. As detailed in Chapter 22, the cure was simply to stay steadily in the Chavadi. This place was old, dilapidated, and filled with garbage, knee-deep holes, dampness, and various creatures like lizards and scorpions. Despite these miserable conditions that would seem to worsen rheumatism, Amir was instructed to accept Baba's word as the sole medicine and reside there for nine months, which he did with faith.
