What were some of the extraordinary yogic practices and supernatural abilities attributed to Sai Baba in this chapter?

In Chapter 7, the author describes some of Sai Baba's remarkable abilities, highlighting his mastery over his physical form. It specifically mentions his practice of Khanda-yoga, which involved the disjointing of his limbs. The text states that sometimes his hands, feet, and head were separated from his body and then joined back together as before. In addition to this, the chapter notes his experiments with internal cleansing techniques like Dhauti, which involves cleansing the stomach. These accounts are presented as evidence of his extraordinary nature and how he even bore the sufferings of his devotees by wearing out his own body.
