What specific instructions did Baba give Amir Shakkar about staying in the Chavadi, and how did this serve as his 'medicine'?

As Amir Shakkar suffered from rheumatism in the chaotic and damp Chavadi, Baba's only 'medicine' was His word. Chapter 22 recounts Baba's firm instructions to him: "Wind, rain, or dampness, whether the place is high, low, or deep—do not weigh them." In essence, Baba commanded him to completely disregard the severe external discomforts. By accepting this command, Amir was able to find happiness in his situation despite the contrary conditions. His faith in Baba's word transformed the ordeal, allowing him to stay for nine months. The instruction was a test of faith, where the healing was not physical but spiritual, contingent on his obedience and trust in Sai's wisdom over his own perceptions of hardship.
