What was the author's motivation and mindset when undertaking the writing of the Shri Sai Charitra?

According to Chapter 25, the author felt a deep, inner desire to write the life story of Shri Sai but initially felt unqualified for the task. He humbly admits that he lacked the authority, knowledge, or erudition. However, he attributes the entire project to divine inspiration, stating, "He Himself certainly made me write it." The pivotal moment came when Sai gave him the command to "Keep the records," which, as the chapter explains, instantly endowed his "meager intellect with courage and special knowledge," enabling him to begin the sacred work.
