How does the beginning of Chapter 42 introduce its main topics and what does it promise to narrate?

Chapter 42 begins with customary salutations and a brief recap of the previous chapter, mentioning the miraculous protection of Sai's portrait from water and a devotee's desire being fulfilled through a dream. Following this, the chapter explicitly sets its own agenda. As stated in Chapter 42, the author intends to describe Sai's nature, specifically pondering whether his mind was intense or soft. Most significantly, it promises to give the listeners an attentive account of the events leading up to and including Baba's leaving his physical body (Mahasamadhi). This introduction serves to transition from previous stories to the pivotal event of Baba's departure.
