What does Chapter 40 reveal about the origin and inspiration behind the Shri Sai Satcharitra?

Chapter 40 reveals that the inspiration for the Shri Sai Satcharitra is rooted in Sai Baba's actions and a broader divine principle. The author mentions that seeing Sai grinding grain sparked a strong desire to describe all such divine deeds. More profoundly, this chapter states that the entire composition is Sai's own inspiration, intended for the welfare of devotees. It even references the Bhavishyottara Purana to support the idea that God is highly pleased when the praises of His devotees are sung. The author, Hemad, emphasizes that Sai Himself is the one providing the intelligence and stimulus for this work, essentially telling His own story.
