What extraordinary yogic practices of Sai Baba are mentioned in the seventh chapter?

The seventh chapter of the Shri Sai Satcharitra describes some of Sai Baba's remarkable and intense yogic practices, which he undertook for the benefit of others. The text specifically mentions his practice of Khanda-yoga, which is described as the disjointing of his own limbs. In these experiments, Baba would reportedly separate his hands, feet, and head, only to join them back together as they were before. Chapter 7 also lists other practices such as Dhauti and Poti, which are methods for cleansing the stomach. These accounts illustrate how he would wear out his own body and even bear the sufferings of his devotees.
