What are the primary topics covered in Chapter 42 of the Sai Satcharitra?

Chapter 42 of the Sai Satcharitra serves as a prelude to the account of Sai Baba's Mahasamadhi. It begins with praises for the Sadguru, describing him as a 'Wish-fulfilling Tree' who helps devotees cross the 'river of worldly existence.' The chapter emphasizes that by remembering the Guru's feet, all obstacles dissolve and unhappiness turns into happiness. It then explicitly states its intention to describe Sai's nature and, most importantly, provide a detailed account of Baba leaving his body. As this chapter details, the people of Shirdi who enjoyed Baba's company for over half a century were incredibly blessed before this momentous event occurred.
