Can you tell me the story of how Sai Baba helped a man suffering from rheumatism?

The story of Amir Shakkar, who suffered from rheumatism, is a profound example of faith. According to Chapter 22, when Amir came to Sai Baba for a cure, Baba's remedy was not a medicine but an instruction: he was to reside in the old, dilapidated Chavadi. Despite this place being damp, cold, and uncomfortable, Amir stayed for nine months. His unwavering faith in Baba's word served as the true medicine. This ordeal highlights how obedience and trust in Sai, even in the face of contrary external conditions, could lead to spiritual and physical well-being, as Amir was also blessed with Baba's constant company.
