What miracles are briefly recapped at the start of Chapter 42, and what major event does the chapter promise to narrate?

The beginning of Chapter 42 serves as a bridge from the previous narrative by recapping a few of Sai's divine plays. It mentions a sweet story of how Sai's portrait was miraculously protected despite being immersed in water. It also recalls how Sai fulfilled a devotee's desire by appearing in a dream and giving him clear permission to read the Dnyaneshwari. After this recap, Chapter 42 clearly states its primary purpose: to provide an attentive account of the significant event of Sai Baba leaving his physical body, an event that brought immense joy to the people of Shirdi for over half a century to a close.
