The beginning of Chapter 8 mentions Baba's intense practices. What were they, and how does the chapter frame them?

In its introductory salutations, Chapter 8 recaps some of Sai Baba's history, mentioning the intense yogic practices he undertook. The text specifically names Dhauti, Poti, and Khanda-yoga. While this chapter does not go into detail about what these practices entail, it frames them as significant hardships that Baba willingly embraced. The narrative states, "By wearing out his own body, Baba endured many hardships." This phrasing, found in Chapter 8, presents these rigorous disciplines not just as spiritual exercises but as acts of self-sacrifice performed by Baba in his role as the "protector of devotees." It highlights the ascetic foundation of his spiritual power before he became a widely followed Guru.
