How does Chapter 40 transition from discussing the author's role to introducing the next narrative?

Chapter 40 serves as a narrative bridge by concluding its reflections on authorship and setting the stage for the next story. After establishing that Sai is the true author using the puppet analogy, the text signals a shift by stating, 'So be it with this introduction... let us sing of the glory of the Guru-devotee.' The chapter then directly introduces the theme of the upcoming sweet narrative, which is that 'When a devotee offers food with love, it brings supreme satisfaction to Sai.' It further builds anticipation by comparing Sai's love to that of a 'compassionate mother to her infant' and reminding listeners that though Sai's body was in Shirdi, He 'wanders through the three worlds,' hinting at his omnipresence in the forthcoming story.
