What does Chapter 40 reveal about the purpose and power of the Shri Sai Satcharitra itself?

Chapter 40 explains that the Shri Sai Satcharitra serves to illuminate both worldly interests and supreme spiritual goals, making devotees feel fulfilled. The text is presented not as a human creation but as Sai's own story, with the author being a mere instrument. It is believed that hearing these stories of Sai Samarth with love can destroy impurities and sins. The chapter cites the Bhavishyottara Purana to support the idea that God loves hearing the praises of His devotees, reinforcing the book's sacred purpose. Ultimately, the power of the book lies in Sai's own inspiration, as He is the one who performs His own story through its pages.
