How did the narrator, Hemadpant, feel after witnessing Baba grind wheat and what did it inspire him to do?

The narrator, Hemadpant, was filled with 'great wonder' and confusion when he first saw Sai Baba, a detached saint, performing the worldly task of grinding wheat. As he recounts in Chapter 1, the event initially puzzled him, as he couldn't see a reason for it. However, after witnessing the full play and learning its true purpose—the eradication of a cholera epidemic—he was profoundly moved. He marveled at the 'inconceivable cause and effect' of Baba's actions. This experience sparked a deep love in his heart, described as a surge 'like waves... to the ocean of milk,' and inspired him to write the book, the Shri Sai Satcharitra, to sing the sweet stories of Baba's divine plays.
