What prompted Amir Shakkar to leave the Chavadi, and what was the immediate event that occurred after his departure?

Despite the spiritual benefits, Amir Shakkar eventually grew tired of his confinement in the Chavadi. Chapter 22 explains that after nine months, the feeling of being in a prison became overwhelming. The natural human desire for freedom and dislike of dependency led him to think, "Enough of this prison!" Acting on this impulse, he left his assigned place and went to Kopergaon without seeking Sai Baba's permission. Immediately upon his arrival at a Dharmashala there, a strange event unfolded: he encountered a dying Fakir, and the moment Amir gave him water to drink, the Fakir's body became lifeless.
