Why was staying in the Chavadi such a difficult test for Amir Shakkar? What was that place actually like?

Staying in the Chavadi was an extremely difficult test for Amir because the conditions were deplorable and completely contrary to healing rheumatism. Chapter 22 describes the Chavadi as an old, dilapidated structure built by Malik Ambar. It was a place where lizards, house lizards, and poisonous scorpions lived freely. The text also notes that lepers stayed there, garbage was piled in the back, and the ground was uneven with seventeen knee-deep holes. Amir had to endure constant dampness, rain, wind, and cold, which made his mind turmoil and caused the joints of his body to seize up.
