The book's author mentions feeling unqualified to write it. What gave him the confidence to proceed with writing the Shri Sai Charitra?

The author, Hemadpant, expresses in Chapter 25 that he initially felt he lacked the authority, knowledge, or erudition to write the life story of Shri Sai. However, he gained the confidence to proceed because he believed Sai Baba Himself inspired him and gave him a direct command. The text states, "He made me write the book with my own hands to awaken His own devotees." The author felt that at the very moment of this command, his "meager intellect became endowed with courage and special knowledge." He saw the book not as his own creation, but as the grace and "Prasad" of the Saint's feet, which Sai would accept for the salvation of His devotees.
