According to Chapter 40, what is the significance of describing Sai Baba's deeds, such as grinding grain?

The significance of describing Sai Baba's deeds is highlighted in Chapter 40. The author recalls the image of Sai, a saint, setting up a grinding stone and grinding grain, an act that filled the author's mind with wonder. This specific memory is identified as 'the root of this book,' suggesting it sparked the initial inspiration. The chapter conveys a strong belief that describing such deeds helps to destroy impurities and sins. To support this, it mentions that God (Hari) is even more pleased when someone sings the praises of His devotees than praises of Himself. This idea, which Chapter 40 notes is supported by the Bhavishyottara Purana, frames the entire Satcharitra as a sacred act of devotion for the spiritual welfare of all.
