How does the author describe his motivation and qualifications for writing the Shri Sai Satcharitra in Chapter 25?

The author explains that the desire to write the life story of Shri Sai arose in his heart. According to Chapter 25, he initially felt he lacked the necessary authority, knowledge, or erudition for such a significant undertaking. However, he conveys that Sai Baba himself provided the inspiration and, in the author's words, "made me write the book with my own hands to awaken His own devotees." The pivotal moment came with Sai's command to "Keep the records," which the author states instantly endowed his "meager intellect" with courage and special knowledge, assuring him that Sai would accept the work for the salvation of his followers.
