What was the 'medicine' Sai Baba prescribed for Amir Shakkar's rheumatism, and what were the conditions of this treatment?

When Amir Shakkar sought a remedy for his rheumatism, Sai Baba prescribed a unique and challenging treatment. As detailed in Chapter 22, the 'medicine' was not a physical substance but Baba's command to stay steadily in the Chavadi. This directive required Amir to live in a dilapidated, damp, and unsanitary building filled with creatures and garbage for nine months. The conditions were contrary to physical healing, but Baba's firm words were to ignore the discomfort. The true medicine was accepting Baba's word with absolute faith, which Amir did, staying happily despite the external hardships.
