According to Chapter 25, what is the author's motivation and justification for writing the Shri Sai Satcharitra?

In Chapter 25, the author explains that the motivation for writing the Shri Sai Satcharitra came directly from Sai Baba himself. The author humbly admits to lacking the necessary "authority, knowledge, or erudition" for such a task. However, he states that Sai inspired him, a "poor soul," and "made me write the book with my own hands to awaken His own devotees." The chapter describes how the author's meager intellect was endowed with courage and special knowledge upon receiving this divine command. He views the resulting nectar-like life story not as his own work, but as the "grace and 'Prasad' of the Saint's feet," written for the salvation of devotees.
