How does the author of the Sai Satcharitra describe the nature of saints and the role of Sai Baba in the narration of Chapter 24?

In Chapter 24, the author begins by describing saints and Great Souls as being 'always pure, stainless, and without blemish,' comparing their purity to a clear and cloudless sky. Regarding the narration itself, the author expresses a deep sense of humility and surrender. They explicitly state, 'Sai Samarth, the stimulator of intellect, makes me speak these words.' This conveys the belief that the author is merely a channel and that Sai Baba is the true source of the words and their significance. This reinforces the chapter's theme that one must be egoless at the Guru's feet.
