What metaphors are used in Chapter 40 to describe the relationship between Sai, the devotee, and the Satcharitra itself?

Chapter 40 employs several powerful metaphors to illustrate spiritual concepts. To describe the merging of a devotee with the Guru, it uses the analogy of a river and an ocean, which have different names but become one when they meet, with no difference remaining. The chapter states that when a devotee seeks exclusive refuge, Sai dissolves the 'separate feelings of me and you.' Another significant metaphor presented in Chapter 40 is that of the puppeteer and the puppet. Hemadpant describes himself as a 'puppet of Sai, dancing to the pull of His strings,' to explain that Sai is the true author of the Satcharitra, controlling the narrative entirely.
