What extraordinary yogic abilities or physical feats of Sai Baba are mentioned in Chapter 7?

Chapter 7 of the Shri Sai Satcharitra touches upon Sai Baba's profound yogic practices and his ability to endure suffering. It specifically mentions his practice of Khanda-yoga, which is described as the disjointing of his own limbs. The text states that at times his hands, feet, and head would be separated from his body and then joined back together as before. This chapter also references experiments like Dhauti (a cleansing of the stomach) and Poti, illustrating how he toiled, wore out his own body, and even bore the sufferings of his devotees upon himself.
