What was the motivation and divine justification for writing the Shri Sai Satcharitra as explained in Chapter 40?

According to Chapter 40, the motivation for writing the Shri Sai Satcharitra stemmed from a strong desire to describe Sai's divine deeds, with the belief that doing so would destroy impurities and sins. The author was particularly moved by witnessing Sai grind grain. The chapter provides a divine justification by stating that God (Hari) is even more pleased when someone sings the praises of His devotees than when they sing praises of God Himself. To lend this statement authority, the text references the Bhavishyottara Purana where Tripurari (Shiva) confirms this. Ultimately, Chapter 40 makes it clear that Sai Himself inspired and approved the composition for the spiritual welfare of all devotees.
