What are the main themes and events described in Chapter 42 of the Sai Satcharitra?

Chapter 42 of the Sai Satcharitra primarily serves to set the stage for and describe the Mahasamadhi, or the leaving of the body, of Sai Baba. The chapter begins by reflecting on the power of the Guru's grace, referencing how a devotee's desire was fulfilled in a dream and how constant remembrance of the Sadguru's feet dissolves all obstacles. As this chapter explains, its main purpose is to describe Sai's nature and provide a detailed account of his departure. The key event detailed in Chapter 42 is the precise timing of this departure, which occurred in the Shaka year 1840 on Vijayadashami, during the third watch of the day, a date which also coincided with the 9th of the Muslim month.
