Can you explain the contrast between Amir Shakkar's internal faith and the external hardships he faced?

The story of Amir Shakkar in Chapter 22 highlights a profound contrast between his inner state and his outer world. Externally, all conditions were against him: he suffered from rheumatism and was forced to live in a filthy, damp, and dilapidated Chavadi for nine months. Internally, however, he possessed "certain faith." He accepted Baba's harsh command as medicine and stayed happily, viewing the company of Sai as the "Great Prasad." The text explicitly notes this dichotomy, stating that while externally all conditions were contrary, his internal faith ensured that "everything went well."
