What was Sai Baba's unusual prescription for Amir Shakkar's rheumatism, and what were the conditions like?

As detailed in chapter 22, when Amir Shakkar sought relief from his rheumatism, Sai Baba's remedy was not medicine but an instruction: he was to stay steadily in the Chavadi. This was a severe test of faith, as the Chavadi was an old, dilapidated building. It was described as being full of lizards and scorpions, damp, cold, and drafty, with seventeen knee-deep holes and garbage. Lepers also stayed there, and the conditions were so harsh that even a dog would find them intolerable. Baba's firm words were that Amir should not question the place, but accept His word as the true medicine.
