Describe how the narrator's experience watching the wheat-grinding incident inspired him to write a book about Sai Baba.

The narrator, Hemadpant, was profoundly moved by the wheat-grinding episode. According to Chapter 1, witnessing the event and later understanding its true purpose—that Baba was grinding the cholera epidemic, not just wheat—filled him with wonder. He was amazed by the 'inconceivable cause and effect' and struggled to find the balance or connection between the simple act of grinding and the eradication of a disease. This powerful demonstration of Baba's divine play sparked a surge of love in his heart, making him feel an intense desire 'to sing the sweet story of Baba to his heart's content'. This inspiration was the catalyst that led him to write the book, the Shri Sai Satcharitra.
