Can you summarize the main topics and stories introduced at the beginning of Chapter 8 of the Sai Satcharitra?

Chapter 8 of the Sai Satcharitra begins by recapping previous events, such as how Sai Baba appeared in Shirdi and turned a barren land into a beautiful garden. The chapter then outlines the topics it will cover, which include the greatness of human birth, Sai Baba's habit of begging for alms (bhiksha), the dedicated service provided by Baijabai, and the wonder of Baba's meals. As noted in the chapter, it also promises to tell of how Baba, Tatya, and Mhalsapati would sleep together in the Masjid, providing a glimpse into his early life and close relationships.
