What is the primary message conveyed by the author in the introductory sections of Chapter 25 of the Shri Sai Satcharitra?

In Chapter 25, the author conveys that the Shri Sai Satcharitra was written not by his own volition or intellect, but through the direct inspiration and command of Sai Baba himself. The author describes himself as an 'ignorant person' lacking 'authority, knowledge, or erudition,' but explains that Sai Baba 'made me write the book with my own hands to awaken His own devotees.' This chapter emphasizes that the book is a form of 'grace and "Prasad"' from the saint, intended for the 'salvation of His devotees.' The author's main message is one of humility, attributing the entire creative and spiritual force behind the work to Sai Baba, the 'supreme embodiment of mercy'.
