Why did Amir Shakkar eventually leave the Chavadi without permission, and what happened right after he left?

According to Chapter 22, despite the unique spiritual benefits of his stay, Amir Shakkar grew weary of the confinement after nine months. His mind began to desire freedom, and he started to perceive the Chavadi as a prison. This thought, "Enough of this prison!" prompted him to leave without asking for Sai Baba's permission. He abandoned his designated place and traveled to Kopergaon, where he stayed in a Dharmashala. Immediately upon his arrival, he encountered a dramatic situation: a Fakir on the verge of death asked him for water. The moment Amir gave him a drink, the Fakir's body became lifeless.
