How does Chapter 42 use stories from the previous chapter to introduce its main themes?

Chapter 42 begins by recapping two key stories from the previous chapter to set a thematic foundation. It references the wondrous divine play where Sai's portrait was miraculously protected from water damage and how a devotee's desire was fulfilled when Sai appeared in a dream, directing him to read the Dnyaneshwari. As described in Chapter 42, these events serve as powerful examples of the main theme: the efficacy of the Guru's grace. This grace is what removes the fear of worldly existence, dissolves obstacles, and opens the door to liberation, a concept which those prior miracles perfectly illustrate.
