Who does the narrator say is the actual force behind the telling of Sai's stories?

According to the text, the narrator feels they have no authority to truly describe the infinite greatness of saints. Chapter 36 clarifies that the playful Sai Baba himself is the one who takes over and makes his own qualities heard by his devotees, using the speaker as a mere instrument. The chapter states that Sai loves his own stories and constantly provides memories of them, making the listener and speaker a pretext to fulfill the desires of his devotees.
