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

After staying in the Chavadi for nine months, Amir Shakkar grew weary of the confinement. Although he had a firm companionship with Sai, the external circumstances made him feel as if he were in a prison. According to Chapter 22, his mind began to desire freedom and he thought, "Enough of this prison!" Without seeking Sai Baba's permission, he abandoned his designated place and went to Kopergaon. The text then describes a startling event: upon arriving at a Dharmashala in Kopergaon, Amir encountered a Fakir on the verge of death who asked for water. The very moment Amir gave him water to drink, the Fakir's body became lifeless.
