Can you explain the author's perspective on his own role in writing the Shri Sai Satcharitra, as conveyed in Chapter 50?

In Chapter 50, the author, Hemad, expresses deep humility regarding his role in composing the Shri Sai Satcharitra. He questions his own ability to describe Sai's glory, asking, "What power do I, a wretched one, have to describe his glory?" He firmly believes that the book is not a product of his own intellect or skill. Instead, he asserts that Sai Baba himself is the true author, stating, "He himself, out of love for his devotees, reveals this book through grace." This perspective positions the author as a mere instrument or channel, with Sai being the divine source of the stories and teachings contained within the sacred text, a sentiment clearly expressed throughout this chapter.
