Can you summarize the preview of topics given at the beginning of Chapter 8?

Certainly. The start of Chapter 8 of the Sai Satcharitra outlines the key stories and teachings that will be presented. After a brief salutation, it promises to delve into the greatness of human birth and the impermanence of the body. More specifically, it sets the stage to describe Sai Baba's daily routine of begging for alms (bhiksha), the dedicated service rendered to him by a devotee named Baijabai, and the wonder surrounding his meals. The introduction also mentions that the chapter will narrate how Baba, Tatya, and Mhalsapati used to sleep together in the Masjid and how Baba would visit Khushalchand's home in Rahata.
