Why does the author of the Sai Satcharitra claim to be just a pretext for the stories being told?

In Chapter 36, the author expresses deep humility regarding their role in narrating the life of Sai Baba. The author questions their own authority to describe the infinite greatness of saints, stating that the "playful Sai himself takes over and makes his own qualities heard by his devotees through someone." This reflects the belief that the author is merely an instrument or a channel. The text reinforces this by saying Sai makes the "listener and speaker a mere pretext" to fulfill the desires of devotees. This conveys that the true narrator is Sai himself, who uses the author to spread his stories and grace.
