The text says Baba's medicine was 'only His word.' How did this 'medicine' work for Amir's rheumatism in such an unhealthy place?

For Amir Shakkar's rheumatism, Baba's 'medicine' was not a physical substance but His divine command and the faith it inspired. Chapter 22 explains that Baba instructed Amir to stay in the damp, cold Chavadi, an environment that should have worsened his condition. Baba's firm words were to ignore the wind, rain, and dampness. Amir's healing and well-being stemmed from his complete acceptance of this command. The power of this 'medicine' lay in Amir's unwavering internal faith, which transcended the adverse physical circumstances and ensured that, as the text says, 'everything went well.'
