Describe the events that led Amir Shakkar to leave the Chavadi and the immediate, strange encounter he had afterward.

The narrative in Chapter 22 recounts that after staying in the Chavadi for nine months, Amir Shakkar grew tired of the confinement. Feeling it was a prison and desiring freedom from dependency, he decided to leave his regular place without seeking Sai Baba's permission. He traveled to Kopergaon and stayed in a Dharmashala. The text describes a strange and immediate event that occurred there: 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, his body became lifeless.
