Describe the harsh conditions of the Chavadi where Sai Baba instructed Amir Shakkar to stay for his rheumatism.

According to Chapter 22, the Chavadi was an extremely inhospitable place. It was described as an old, dilapidated building constructed by Malik Ambar, where pests like lizards, house lizards, and poisonous scorpions lived freely. The text mentions that lepers also stayed there, and dogs would eat leftovers on the premises. The back part was filled with garbage and seventeen knee-deep holes. The environment was characterized by constant dampness from below, rain from above, and a chaotic mix of wind and cold, making it a severe trial. Amir found the conditions miserable, yet Baba insisted he stay there as a remedy.
