Can you tell me about the devotee who was cured of rheumatism by staying in a dilapidated place?

This story is about Amir Shakkar, who was suffering from rheumatism. As detailed in Chapter 22, he approached Sai Baba for a remedy. Baba instructed him to stay in the Chavadi, which was an old, dilapidated building. The conditions were terrible, with dampness, cold, garbage, and even scorpions. Despite these hardships, Amir stayed there for nine months out of faith in Baba's word. This was Baba's unique treatment, and although Amir was forbidden from even visiting the Masjid, his steady faith and residence in the Chavadi, as per Baba's command, was the medicine for his ailment.
