Which specific instructions did Sai Baba give Amir Shakkar regarding the cure for his rheumatism and his stay in the Chavadi?

As a remedy for his rheumatism, Sai Baba gave Amir Shakkar a very specific and unconventional set of instructions. Initially, as Chapter 22 narrates, Baba told him he should stay steadily in the Chavadi. When Amir was miserable due to the terrible conditions, Baba gave him firm words, instructing him not to weigh or be concerned about the environmental factors, whether it was wind, rain, dampness, or if the ground was high, low, or deep. A further restriction was that Amir was forbidden from even coming to the Masjid for a vision during his nine-month stay in the Chavadi, with Baba's word being the only medicine prescribed.
