How does the author of the Sai Satcharitra describe his own role in writing the book?

In Chapter 36, the author takes a very humble stance regarding his role in narrating the stories. He explicitly questions his own authority and dismisses what he calls the "'I-ness' (ego) of the speaker." Instead, he explains that the "playful Sai himself takes over and makes his own qualities heard by his devotees through someone." This suggests the author sees himself as a mere instrument or a pretext. The chapter reinforces this by stating Sai makes the listener and speaker a pretext to fulfill the desires of devotees, implying the entire work is orchestrated by Sai's will, not the author's personal skill.
