How can staying in a damp, windy place be considered a 'remedy' for rheumatism in the story of Amir Shakkar?

In this story from Chapter 22, the 'remedy' for Amir's rheumatism was not a physical treatment but a profound test of faith and surrender. Baba's medicine was explicitly His word, not a conventional cure. The conditions of the Chavadi were externally contrary to healing, with dampness and cold that would typically worsen rheumatism. However, the cure was in Amir's internal state—his 'certain faith' and his obedience in accepting Baba's word as the ultimate medicine. By enduring the nine-month stay happily despite the hardships, his deliverance was achieved through spiritual surrender rather than physical therapy.
