Can you give me an overview of the main topics discussed in Chapter 8 of the Sai Satcharitra?

Chapter 8 of the Sai Satcharitra begins by saluting various deities and recapping the previous chapter. It then introduces the key themes for this chapter, which include a deep philosophical discussion on the greatness and purpose of human birth. As outlined in the text, it also promises to cover Sai Baba's practice of begging for alms (bhiksha), the dedicated service rendered to him by Baijabai, the wonder of his meals, and details about his life in the Masjid, such as how he slept there alongside Tatya and Mhalsapati. The chapter also mentions Baba's visits to Khushalchand's home in Rahata.
