Can you tell me about the supernatural physical feats or yogic practices Sai Baba performed, as described in chapter 7?

Chapter 7 of the Shri Sai Satcharitra describes Sai Baba's complete mastery over his physical form through advanced yogic practices. The text specifically mentions his practice of Khanda-yoga, an astonishing feat where he could disjoint his limbs—separating his hands, feet, and head from his torso—and then rejoin them as if nothing had happened. In addition to this, the chapter notes he performed other difficult practices like Dhauti, a method for cleansing the stomach. These accounts are presented as examples of how Baba toiled for the benefit of others and even bore the sufferings of his devotees, using his body in extraordinary ways.
