Why was the author of the Satcharitra so moved by the sight of Baba grinding wheat?

The author, Hemadpant, expresses his profound wonder in Chapter 1 upon seeing Baba grinding wheat. Initially, he was puzzled as to why a detached saint with no possessions would engage in such an activity. His astonishment grew immensely when he learned the true purpose: Baba was not grinding wheat, but the cholera epidemic itself, thereby saving the village. The author notes the 'inconceivable cause and effect' and the mysterious connection between wheat and disease. This powerful and miraculous event filled his heart with love and served as a direct inspiration, making him feel that he must write a book to sing the 'sweet story of Baba to my heart's content.'
