Why did Amir Shakkar eventually leave the Chavadi, and what happened immediately after he went to Kopergaon?

After staying in the Chavadi for nine months, Amir Shakkar grew tired of the confinement. Chapter 22 explains that his mind began to desire freedom, and the place started to feel like a prison. Without seeking Sai Baba's permission, he abandoned his spot and went to a Dharmashala in Kopergaon. The text describes a dramatic event that occurred right after: he encountered a Fakir on the verge of death from thirst. Amir felt pity and gave him water, but the moment the Fakir drank it, he became lifeless.
