Why did Amir Shakkar leave the Chavadi, and what happened right after he left?

According to Chapter 22, after staying in the Chavadi for a long time, Amir Shakkar grew weary of the confinement. Even with the constant company of Sai, the place began to feel like a prison, and his mind desired freedom from the dependency. Feeling that he had had enough of the prison, he made the decision to leave without seeking Baba's permission. He abandoned his assigned place and went to Kopergaon, where he stayed in a Dharmashala. Immediately upon his arrival, a significant event occurred: he encountered a Fakir on the verge of death from thirst. When Amir gave the man water, the Fakir died the moment he drank it.
