What led Amir to leave the Chavadi, and what happened immediately after he left without permission?

Despite the spiritual benefits of being near Sai Baba, Amir Shakkar eventually grew tired of his confinement in the Chavadi. Chapter 22 states that his mind desired freedom and he began to see his situation as a 'prison.' This feeling of being in a prison and the desire for independence led him to make a decision. Without seeking or receiving Sai Baba's permission, Amir abandoned his designated place in the Chavadi and traveled to Kopergaon, where he stayed in a Dharmashala. Immediately upon his arrival there, he encountered a miracle: a Fakir on the verge of death from thirst, to whom he gave water.
