What does Amir Shakkar's experience in the Chavadi reveal about the nature of faith versus physical hardship?

Amir Shakkar's experience, as narrated in Chapter 22, serves as a powerful lesson on the supremacy of faith over physical hardship. He was suffering from rheumatism and was made to stay in a place that was damp, cold, and filthy—conditions that were completely contrary to his physical well-being. However, the narrative states that because he had 'certain faith' internally, 'everything went well.' He accepted Baba's word as his medicine and stayed happily. This episode illustrates that with unwavering faith in a Guru's command, external adversities become powerless and one can find well-being even in miserable circumstances.
