How does the author of the Shri Sai Satcharitra describe his inspiration for writing the book in Chapter 25?

In Chapter 25, the author explains that while the desire to write the life story of Shri Sai arose in his heart, he felt he lacked the necessary authority or knowledge. He attributes the entire endeavor to Sai Baba Himself, stating that Sai inspired him and 'made me write the book with my own hands to awaken His own devotees.' The author recounts that when Sai gave the command to 'Keep the records,' his meager intellect was immediately endowed with courage and special knowledge. He views the resulting nectar-like life story not as his own work, but as the grace and 'Prasad' from the Saint's feet, intended for the salvation of devotees.
