How did the narrator reflect on the symbolism of Baba grinding wheat to cure an epidemic?

The narrator, after witnessing the grinding of wheat and learning its true purpose, was filled with profound wonder. Chapter 1 describes the narrator's struggle to reconcile the action with its outcome, pondering, "how should one coordinate cause and effect? What could be the connection? What is the relation between wheat and disease?" This experience of seeing the "inconceivable cause and effect" of Baba's actions inspired a deep love and the desire to write a book about his sweet stories. The event highlighted Baba's mysterious methods, which transcended ordinary logic and demonstrated that his plays, though seemingly strange, were always for the benefit of others and could only be understood with patience.
