How does the story of the Patil in Chapter 13 illustrate the nature of faith and Sai Baba's unconventional methods?

Chapter 13 details the experience of a Patil who was cured of a disease through two strange dreams. In one, a teacher beat a student, and in the other, a man ground his chest with a stone. Despite the agony in the dreams, the Patil awoke completely healed, realizing it was Sai Baba's grace. This experience, described as a "punishment" that was "clearly beneficial," strengthened his faith immensely. He understood that Sai's ways are "inconceivable and unfathomable." His response was total surrender and gratitude, demonstrating that faith sometimes requires accepting that divine help can come in mysterious and even seemingly harsh forms.
