What was the true nature of the 'medicine' Baba gave for Amir's rheumatism, and how was faith involved?

The 'medicine' Sai Baba provided for Amir's rheumatism was not a physical remedy but was His divine word and command. As Chapter 22 explains, 'Baba's medicine was only His word.' The entire treatment consisted of obeying the instruction to stay in the harsh and uncomfortable environment of the Chavadi for nine months. Externally, all conditions like dampness and cold were contrary to healing rheumatism. However, the cure was dependent on Amir's internal state. The text emphasizes that 'internally there was certain faith; because of that, everything went well.' Amir's healing was directly linked to his ability to accept Baba's word as the absolute remedy and maintain faith despite the physical hardships.
