Can you provide a summary of the main topics covered in Chapter 8 of the Sai Satcharitra?

Chapter 8 of the Sai Satcharitra begins by saluting various deities and recapping the previous chapter's points about Sai's origins and the transformation of Shirdi. It then introduces the key topics for the current chapter, which include Sai's practice of begging for alms (bhiksha), the devoted service rendered by Baijabai, the wonder of Baba's meals, and how Tatya, Baba, and Mhalsapati would sleep together in the Masjid. A significant portion of the chapter, as described in its introduction, is dedicated to a philosophical discourse on the true purpose of human life, contrasting it with mere animal existence and emphasizing the importance of spiritual realization over mundane activities.
