Why did the author of the Shri Sai Satcharitra write the book? Did he feel he was qualified?

The author explains in Chapter 25 that a desire arose in his heart to write the Shri Sai Charitra, and he believed that Sai Baba Himself made him write it to awaken His devotees. The author openly admits that he felt he lacked the authority, knowledge, or erudition for such a significant task. However, he states that when Sai gave him the command to "Keep the records," his meager intellect was suddenly endowed with courage and special knowledge. He ultimately viewed the book not as his own creation but as the grace and "Prasad" of Sai's feet, a nectar-like life story written for the salvation of devotees.
