What was Sai Baba's remedy for Amir Shakkar's rheumatism, and what were the living conditions he had to endure?

According to Chapter 22, when Amir Shakkar detailed his affliction with rheumatism and prayed for deliverance, Sai Baba's remedy was simply His word. Baba instructed Amir to stay steadily in the Chavadi. This prescription was a profound test of faith, as the Chavadi was an old, dilapidated building filled with hardships. The text describes it as a place where lizards and scorpions lived freely, lepers stayed, and dogs ate leftovers. It was damp, uneven, full of garbage and holes, and exposed to wind and cold, making it a miserable place for someone suffering from rheumatism. Despite these contrary external conditions, Amir was told to accept Baba's word as his medicine.
