Chapter 7 mentions some of Baba's extraordinary yogic practices. Could you describe these?

Chapter 7 of the Shri Sai Satcharitra details some of Sai Baba's incredible yogic abilities, which demonstrated his complete mastery over his physical body. The text mentions his practice of Khanda-yoga, a state where his limbs, such as hands, feet, and head, would become disjointed and then reattached as if by will. Additionally, it refers to experiments like Dhauti, a cleansing of the stomach, and Poti. These practices, as described in this chapter, highlight how Baba would sometimes wear out his own body, even bearing the sufferings of his devotees, which showcased his profound spiritual power and compassion.
