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

According to Chapter 22, Amir Shakkar grew weary of his long confinement in the Chavadi. Although he had the benefit of Sai's companionship, the feeling of being in a prison became overwhelming. The text explains that the "mind desires freedom," and the thought "Enough of this prison!" arose in Amir's mind. Consequently, he left his assigned place without seeking Baba's permission and traveled to Kopergaon, where he stayed in a Dharmashala. Immediately upon his arrival, a strange event occurred: 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 died.
