According to the introduction of Chapter 36, what is the role of the speaker and listener in the telling of Sai's stories?

Chapter 36 of the Shri Sai Satcharitra clarifies that both the speaker and the listener are merely pretexts or instruments in the narration of Sai's life. The text asserts that the ego, or "I-ness," of the speaker is set aside as "the playful Sai himself takes over and makes his own qualities heard by his devotees through someone." It is Sai who provides the memories and orchestrates the telling. The chapter states that he uses this process of narration, involving both the speaker and the listener, as a means to fulfill the desires of his devotees, thereby purifying the mouths of the speakers and the ears of the listeners everywhere.
