How does the author of the Shri Sai Charitra describe his own experience and motivation for writing the book?

In Chapter 25, the author humbly reflects on the process of writing the Shri Sai Charitra. He admits that he felt he lacked the authority, knowledge, or erudition for such a monumental task. However, he credits Sai Baba directly, stating that Sai Himself inspired him, a 'poor soul,' and gave him the command to 'Keep the records.' The author explains that this divine inspiration endowed his 'meager intellect' with courage and special knowledge. He believed he was merely an instrument, writing the book with his own hands to awaken Sai's devotees, and that Sai would accept the book for their salvation. He views the work not as his own but as the grace and 'Prasad' of the Saint's feet.
