How did the author of the Shri Sai Charitra describe his own role and inspiration for writing the book?

In Chapter 25, the author explains that the desire to write the Shri Sai Charitra arose in his heart, but he felt he was merely an instrument for Sai Baba's will. He humbly admits that he lacked the authority, knowledge, or erudition for such a task, referring to himself as a "poor soul" and an "ignorant person." He firmly believed that Sai Baba Himself inspired him and "made me write the book with my own hands to awaken His own devotees." The author felt his intellect was endowed with courage and special knowledge only because Sai commanded it, viewing the work as the grace and "Prasad" of the Saint's feet.
