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

Despite the spiritual benefits, Amir Shakkar eventually grew weary of his nine-month confinement in the Chavadi. Chapter 22 states that the stay began to feel like a prison to him, and his mind longed for freedom from this dependency. A thought, "Enough of this prison!" compelled him to act. Without seeking Sai Baba's permission, he abandoned his post and traveled to Kopergaon, staying in a Dharmashala. Immediately upon his arrival, a strange event occurred: he encountered a Fakir who was near death and begging for water. Amir felt pity and gave him a drink, but the very moment the Fakir drank the water, he became lifeless.
