Can you summarize the story of Amir Shakkar's nine-month stay in the Chavadi?

Amir Shakkar, who was afflicted with rheumatism, was commanded by Sai Baba to stay in the old, run-down Chavadi for a period of nine months. According to Chapter 22, the living conditions were dreadful, with dampness, drafts, and vermin. Despite this, Amir stayed happily because he had complete faith in Baba's word, which he considered his medicine. A key restriction was that he was forbidden from going to the Masjid for darshan. However, he was still blessed with Baba's vision daily as Baba passed the Chavadi on His morning and evening rounds. On alternate nights when Baba stayed in the Chavadi, they would even converse privately.
