Based on Chapter 25, what was the author's motivation and perceived role in writing the Shri Sai Satcharitra?

According to Chapter 25, the author felt they lacked the authority, knowledge, or erudition to write the Shri Sai Satcharitra. However, a desire arose in their heart, and they firmly believed that Sai Baba Himself inspired and compelled them to write it. The text states, "He Himself certainly made me write it." The author saw their role as a humble instrument, chosen by Sai to create this record for the salvation and awakening of His devotees. Chapter 25 explains that the author's meager intellect was endowed with courage and special knowledge through Sai's command, viewing the resulting book not as their own work but as the "grace and 'Prasad' of the Saint's feet."
