How did Sai Baba react to the narrator's inner thoughts of jealousy regarding Sathe's quick spiritual progress?

The narrator felt a pang of jealousy, wondering why Sathe received spiritual fruit in just seven days while his own years of devotion seemed less fruitful. Chapter 18 reveals that Sai Baba, being the all-knowing Guru, immediately perceived these thoughts without a word being spoken. Instead of a direct verbal lesson, Baba employed a practical one. He sent the narrator to Shama's house on the pretext of collecting fifteen rupees in Dakshina, setting in motion a sequence of events designed to teach the narrator a personal lesson about discipline.
