What was Baba's specific instruction to Amir about enduring the hardships of the Chavadi, and how did Amir respond?

When Amir Shakkar was struggling with the miserable conditions of the Chavadi, which was damp, cold, and uncomfortable for his rheumatism, Sai Baba gave him a specific and firm instruction. As chapter 22 recounts, Baba's words to him were: "Wind, rain, or dampness, Whether the place is high, low, or deep—do not weigh them." Amir's response was one of complete surrender and faith. He accepted Baba's word as his medicine and the company of Sai as the 'Great Prasad'. This internal faith allowed him to overcome the contrary external conditions and, as chapter 22 states, he stayed there happily for nine months, demonstrating the power of trusting the Guru's command.
