How did the incident of the wheat grinding inspire the author, Hemadpant, to write the book?

The incident of Sai Baba grinding wheat had a profound impact on the author, Hemadpant. As he recounts in Chapter 1, witnessing the event filled his soul with wonder. He was particularly struck by the inconceivable connection between the cause (grinding wheat) and the effect (the cessation of a cholera epidemic). He struggled to comprehend the relationship between the two, which made him feel that he should write a book. This mysterious and powerful act by Baba sparked a surge of love in Hemadpant's heart, creating a deep desire to 'sing the sweet story of Baba to his heart's content,' which ultimately led to the creation of the Shri Sai Satcharitra.
