Amir Shakkar had rheumatism. What was Baba's 'medicine' for his condition and what did it entail?

Amir was suffering from rheumatism, and all external conditions in the Chavadi were contrary to his health. As detailed in Chapter 22, the place was extremely damp, windy, and cold. However, Baba's remedy was not a physical substance; the text states that Baba's "medicine was only His word." Baba gave him firm instructions not to worry about the wind, rain, or dampness of the place. Amir's treatment was to accept Baba's word as the Great Prasad and stay in the Chavadi happily for nine months, holding certain faith internally despite the external hardships.
