What was Amir's internal attitude towards staying in the miserable Chavadi, and what sustained him through the ordeal?

Initially, Amir became very miserable upon seeing the dreadful conditions of the Chavadi, a place of dampness, filth, and chaos. However, as Chapter 22 recounts, his internal state was one of certain faith in Sai Baba. He accepted Baba's word as his only medicine and considered the company of Sai to be the "Great Prasad." Despite all the external conditions being contrary to healing, it was this unwavering internal faith that sustained him. He ultimately accepted his situation and stayed there happily for the prescribed nine months, trusting completely in Baba's command.
