Chapter 46 seems to act as a link between other stories. What does it mention about the previous chapter and what does it promise to tell next?

Yes, Chapter 46 of the Sai Satcharitra serves as a narrative bridge. It begins by recapping the key events from the previous chapter, specifically mentioning the reading of the Bhagavat by Dixit and the miracle experienced by a devotee named Anandrao Pakhade in a dream, which demonstrated the glory of devotion to Sai. After these reflections, the chapter transitions by preparing the reader for a new story. It promises to narrate a 'novel story' that is filled with miracles at every step, one that will cause the listener to be overcome with deep emotion and joy.
